ATOM-16273 Compiling SceneSRG before updating it can cause a gpu crash
Changes include:
1. Removed Scene::SetShaderResourceGroupCallback() function and clean up code which use this function.
2. Moved SceneTimeSrg.azsli to RPI's DefaultSceneSrg folder and setup the constants in RPI::Scene
3. Add AZ::Event for Scene's update srg event which features and update scene srg at proper place
4. UpdateTransformServcie FP to use PrepareSceneSrg event handler.
5. Clean up shaders and srgs used in project templates.

* Fixed log2 shaper equations. Added bspline sampling for lut. Added options for custom log2 or linear lut with custom exposure ranges.

* Added support for PQ shaper. Added shader option & cvar for lut sampling quality. Fixed issues in the blend lut shader that were causing considerable quality loss. No longer always changing to the log2 1000 nit shaper when blending luts - if the source luts all use the same shaper, keep using that shaper in the blended lut.

First version of temporal antialiasing and contrast adaptive sharpening for GA. Works well in most cases but still has a few issues that will need additional time. This is only the passes and shaders with no exposure to the editor. TAA and CAS can be turned on by enabling their respective passes in the pipeline.
All of the code has been previously reviewed in smaller PRs into the taa_staging branch:
aws-lumberyard-dev#29
aws-lumberyard-dev#53
aws-lumberyard-dev#73
aws-lumberyard-dev#79
aws-lumberyard-dev#84
Main issues:
- Bloom doesn't play nice with TAA and seems to greatly amplify any flickering
- AuxGeom jitters with the camera, so TAA doesn't currently work well in editor
- Transparencies don't have correct motion vectors. History rectification keeps this from looking too bad, but could still be improved
- There is still more that could be done to inhibit flickering, usually from specular aliasing
- Motion vectors aren't correct on POM unless PDO is turned on, which can result in some blurring during motion.
- SSAO can contribute to flickering in its default half res configuration. Changing this to full res mitigates the problem.
Squashed merge of the following:
* [ATOM-13987] Initial checkin of Taa pass.
* TAA pass setup WIP. (does not work yet due to pass configuration issues).
* Taa WIP - Camera motion vectors fixed and hooked up. TAA does simple reprojection and rejection based on depth.
* Small update to use lerp and add some comments.
* Fix issue with attachments not being set up on bindings at initialization. Fixing issue with half-pixel offsets in TAA shader
* - Motion vector passes now use the same output with mesh motion vectors overwriting camera motion vectors.
- Taa pass now works with multiple pipelines.
- Cleaned up TAA shader a bit.
* Fixes from PR review.
* Adding check for multiple attachments of the same name with different resources in Pass::ImportAttachments().
* Adding camera jitter with configurable position count. Updated TAA to blend in tonemapped space.
* Fixes from PR review. Fixing camera motion vectors for background (infinite distance)
* Updates to taa shader from PR review
* Adding a rcp input color size.
* Fix comment on PassAttachment::Update()
* Updates for PR review.
* Fixing missing const on the FrameAttachment* in Pass's call to FindAttachment()
* Taa WIP - Adding filtering to both the current pixel and history. Adding rectification based on variance clipping. Adding some basic anti-flickering. Removing rejection based on depth.
* Updates from PR code review. Mostly better commenting and naming.
* Adding contrast adaptive sharpening based on AMD FidelityFX CAS to help with the softness added by TAA.
* Changing to using luminance for sharpening instead of just green. Added some comments.
* Moving Taa's NaN check to a better location. Disabling TAA and sharpening in prep for check in.
* Updates from PR feedback.
* ATOM-15658 Better option of CreateCommonBuffer requires unique buffer name
- Change the CreateCommonBuffer function to not require an unique name by default.
- Remove the code for generating unique buffer names.
- Add buffer name to BufferAsset so it can be used for device object name instead of using asset file name.
- Change RPI::Buffer to use BufferName_AssetUuid as attachment id.
The crash was because the "BlendColorGradingLutImageAttachmentId" attachment got imported to attachment database twice.
This fix avoids import this attachment twice. It also avoid crash but only report a warning if an imported attachment wasn't used in any scope.
Enable both RHI and RPI validation (no visiable performance impact observed.
