* Added clone methods for the buffer, model lod and model assets.
* Cloning works via the creators.
* Mesh handle/instance now knows about the model asset it originated from as well as the cloned model asset that we need for instancing until instancing works without the dependencies to the asset ids.
* MeshComponentRequestBus returns the original asset id and the model asset. If you need access to the clone, go by the model.
* Cloth component mesh now gettings its model asset from the model as it needs to work on the clone.
* Moved the requires cloning function from the mesh loader in the mesh feature processor to the mesh component controller.
* As we need the model asset to be loaded before we can check if it requires cloning or not, we couldn't pass in a bool from the controller but had to use a callback.
* Using asset hint instead of asset id for the model lod asset creator error.
* Storing a map of source buffer asset ids and the actual cloned buffer assets rather than just their ids.
* Using the buffer assets from the new map directly and removed the search process in the mesh loop where the asset views are created.
* Fixed the vegetation mocks.
* Using the actor's mesh asset when emitting the on model ready event for the mesh component notification bus.
* Mesh components notifications connection policy changed to adapt to cloned model asset.
* Handling empty meshes in model lod asset creator.
* Removed the requires cloning callback from the mesh feature processor and made it a parameter to the acquire mesh function
* Fixing mocks and unit tests
ATOM-14040 Add Support for Cavity Maps
Replace the "Ambient Occlusion" property groups with "Occlusion" property groups that contain settings for "Diffuse AO" and "Specular Cavity" maps.
Pre-multiplied diffuseAmbientOcclusion into the m_albedo.rgb gbuffer, making room for specularOcclusion to be stored in m_albedo.a
Added new render pipeline connections to connect the albedo gbuffer to the fullscreen reflection passes.
Also fixed ATOM-15297 "StandardPBR_ForwardPass.shadervariantlist Job Fails With Obscure Error"
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).
Remove option from presets
Updated code to select current default options
Will data drive default options with editor settings or settings registry in upcoming tasks
