* Use SampleLevel instead of Sample to sample shadow maps.
This allows shadow code to be used from computer shaders which don't allow Sample. Shadow maps don't have LODs anyways
* Fix some very silly typos
* Refactoring the LTC quad and polygon lights to clip the light to the normal hemisphere before applying the LTC matrix. This prevents specular light leaking from behind the surface. Diffuse and specular contribution are now calculated at the same time to avoid clipping the polygon twice. Added a cheaper diffuse integration function that's accurate enough for diffuse. Also added a commented out alternate specular integration for platforms with poor acos() accuracy.

* Fixed organization of the AssetProcessor SourceAssetBrowser
Assets within the Engine Root were grouped under a '/' entry.
That has been fixed to use the relative path within the engine root for
those assets
Assets outside of the Engine Root, but on the same drive were using
absolute paths before. Now there are child entries that navigate up the
directory hierarchy to those asset locations
* Added ly_enable_gems call to Atom gems targets that are required
The DefaultLevel.prefab contains several Atom components, that require
the Atom RHI, RPI, Common_Feature, ShaderBuilder and AtomLyIntegration CommonFeatures
gems to be enabled in order to successfully process in the
AssetProcessor.
* Added ly_enable_gems call to make the Camera gem required in Tools,
Builders and Clients.
This is needed as the DefaultLevel.prefab contains an Editor Camera
Component
* Adding the ly_enable_gem call to make the Maestro gem required
CrySystem currently requires Maestro to be enabled in order to
initialize
* Added ly_enable_gems call to the SceneProcessing gem to make it required
The SceneCore and SceneData libraries that are part of the core engine
Code folder requires the SceneProcessing gem to be enabled in order to
invoke the InitializeDynamicModule hooks in DllMain.cpp in order to
initialize those libraries.
* Fixed bad argument in comment for Prefab CMakeLists.txt
* Fixed Assert in Asset Builders due to the Atom RPI Builder
The Atom RPI Builder was enabling the Asset Catalog for the ScriptAsset a second time
The Atom Feature Common EditorSystemCommonComponent.cpp which also loads
in the AssetBuilder is enabling the Asset Catalog for the ScriptAsset
Added BehaviorContext reflection to the OutputDeviceTransformType enum
to fix the BehaviorContext errors about reflecting a method that returns
such an enum
* Added TypeId output to the JsonDeserializer report message about missing
ClassData
Previously the report callback would indicate that the target type was
missing Serialization class data, but didn't indicate the TypeId of the
target type
* Added support to the ly_enable_gems function to be able to support
0 gems being enabled.
Updated the Install step for CMake to propagate any ly_enable_gems
within a CMakeLists.txt for a target into the generated CMakeLists.txt
that is made for each installed IMPORTED target
* Adding newline to the end of the Camera Gem CMakeLists.txt
* Fixing target TYPE parameter for actual Gem Modules to use the GEM_MODULE tag instead of MODULE
* Reverting change to the DESTINATION directory for the installed CMakeLists.txt to use the relative path to the installed directory
* Adding the Atom_Bootstrap gem as a required gem
The Client and GameLaunchers required the Atom_Bootstrap gem in order to create the NativeWindow
Added Atom_Feature_Common client module as a runtime dependency of the AtomLyIntegration CommonsFeature client module
* Fixed register.py --all-projects-path and --all-gems-path arguments to
NOT register projects or gems that are within a template folder
Fixed reading of old pre-1.0 o3de_manifest.json files where the
"engines" key was a json array
* Changed how the relative target source directory is calculated when that source directroy resides outside of the engine root.
The final dirname component is used with a unique SHA256 has to form a <dirname>-<8 char SHA256> folder for installing files into
* Adding newline to the end of Atom_Bootstrap CMakeLists.txt
* Moving ly_enable_gems variants for Tools and Builders inside of PAL_TRAIT_BUILD_HOST_TOOLS block
* Adding a comment to AWSCore.ResourceMappingTool target to indicate that it is not a GEM_MODULE.
Furthermore it cannot be loaded with the Gem system because the library is in a different directory the executable

Removed the parallax invert flags and instead all the materials assume displacement is always specified as heightmaps.
Updated property naming, tooltips, and shader variable names to reflect this.
Updated ParallaxMapping.azsli to treat depthOffset as an offset in depth value rather than an offset in height value, so it matches the fact that ParallaxMapping.azsli always operates in depth values rather than height values.
Added a loop to the skin shader that will sample from wrinkle masks, multiply them by a weight, combine them, and use them instead of vertex colors for wrinkle map blending
Added an array of masks, an array of weights, and a wrinkle mask count to the DefaultObjectSrg. -Will create a follow up task to handle this a better way.
Removed motion vector (for now) from skin.materialtype since we're not using them, and removed depthtransparent since skin doesn't support transparency
Added an interface to the MeshFeatureProcessor to get the object srg
Wrapped srg->Compile in if(srg->IsQueuedForCompile()) to prevent compiling twice --This doesn't stop a race condition if both happen at the same time, but that is at least far less likely. It will need a better solution later.
Added a function to the MorphTargetExporter that will check to see if a texture that matches the blend shape name exists in a particular folder, and adds a reference to that image to the MorphTargetMetaAsset --Only supports .tif, and doesn't automatically re-process the .fbx if the folder is updated. These can be improved in later iterations
Added a null check in MaterialTypeSourceData.cpp to fix a crash I ran into
Added a for loop in two places to look for the first submesh that has a morph target, instead of just using the first to check if a lod has morph targets or not. --I have a better fix for this, but it involves more areas of the code, so I'm saving that for another change.
Modified AtomActorInstance to look for any morph targets that have a wrinkle mask reference
Then each frame, for any morph targets with non-zero weights that also have wrinkle masks, it updates the mask array, weights, and count on the object srg.
Refactored StandardMultilayerPBR to collate all the code for each layer into a couple structs and utility functions. This makes the code easier to maintain, and in particular will make it easy for me to add Enable flags for the layers in a subsequent commit.
Also removed subsurface scattering and translucency from StandardMultilayerPBR, according to ATOM-4120 "Stabilize Standard PBR Regarding Subsurface and Translucency".

WIP refactor of StandardMultilayerPBR to collate the code for each layer. Also removed subsurface scattering from multilayer.
Added Height Offset support to StandardMultilayerPBR.materialtype.
In order to make this work, I updated the GetDepth callback function to support the option of returning absolute depth values rather than relative depth values. Although I could have done transformations inside the GetDepth function, having this as absolute cleans things up a lot. StandardMultilayerPBR_Parallax.lua functor code now populates the MaterialSRG with displacement min/max values, instead of having to normalize the depth factors for each layer. I think this is easier to understand and work with.
Added Height Offset to each layer of StandardMultilayerPBR.
Updated the naming and description for the parallax factor in each layer, to match the other material types.
I removed the global "factor" material property because it doesn't seem applicable anymore since we have per-layer height offset. We can always add some form of this later if customers ask for it.

Local WIP changes to get a DepthResult struct set up for the GetDepth functions.
Added parallax "Height Offset" properties to StandardPBR and EnhancedPBR.
- Refactored depth pass and shadow pass shaders to use the GetParallaxInput utility.
- Updated EnhancedPBR.materialtype to match the parallax controls and functors of StandardPBR.materialtype.
- Updated EnhancedPBR's shadow pass shader to apply a ShadowMapDepthBias because I noticed StandardPBR is doing this, so I made them match.
- Updated StandardPBR and EnhancedPBR to both use the depth offset property, as well as heightmap clipping debug view.
- Note that depth offset is not supported in StandardMultilayerPBR yet, it's hard-coded to 0 for now.
- Note that I plan to rename a lot of the "depth" terms to "heightmap" or "displacement" in an upcoming commit.
Note there were significant conflicts in LightingModel.azsli and StandardPBR_ForwardPass.azsl. I only did basic resolves of these conflicts, mostly preserving the changes from main and distarding the changes in the local branch. The shaders are not compiling at this point, and of course the tests are not passing. I will fix up the code to make corrections in a separate commit, to make it easier to review those changes separate from this merge.
Added new input attachment to the fullscreen reflection pass to receive the "ambient" gbuffer.
Added diffuse and specular occlusion to the Skin material type; it was missing before.
ATOM-14040 Add Support for Cavity Maps
Testing:
AtomSampleViewer automation, with updates that will be submitted in that repo.
Manual testing in Material Editor.
Built all AtomTest assets and opened a few test levels, with updates that will be submitted in that repo.
Made local copies of the occlusion test materials and changed replaced the material types with EnhancedPBR and Skin, and got identical results (with clear coat disabled since it works different in EnhancedPBR and is absent in Skin).
