- Deprecated legacy members from FPooledRenderTargetDesc.
- Deprecated ETextureRenderTarget and removed from RDG.
- TargetableTexture always equals ShaderResourceTexture.
- Simplified render target pool FindFreeElement.
- Create pooled buffers and textures with a known state.

There remain significant visual artifacts in the Virtual Production City map. Lumen has serious issues with multiple views in both single and multi-GPU modes -- I think Lumen data needs to be split per view family to solve this. There is some corrupt geometry in the second view, which may be Nanite or instance rendering related (or something else entirely). To narrow down these issues, I think I'm going to need to extend the DumpGPU feature to be able to do more effective MGPU graphical debugging, since none of PIX, RenderDoc, or NSight work. But at least it doesn't crash now...
Full list of changes:
* CVAR (DC.MultiGPUMode) to override multi-GPU mode for Display Cluster, debug feature copied over from 4.27.
* Barrier and synchronization fixes for RHITransferTextures copied over 4.27. Future work will make RDG handle multi-GPU transitions more seamlessly...
* CVAR (DC.ForceCrossGPUCopy) to force expensive full synchronization and copy of resources cross GPU at the end of each view family render (for debugging). RHITransferTextures upgraded to support copying things besides 2D textures, including other texture resources and buffers.
* AFR temporal fixes from a previous CL (which I moved from my single GPU to multi GPU PC), now improved to avoid some validation asserts in Debug builds (pass inputs not declared, GetParent()->GetRHI() not working because parent not declared to pass).
* Ray tracing (hang): acceleration buffers are branched per GPU, as GPU virtual addresses for resources internally referenced by these buffers may vary per GPU. Needed to add infrastructure to support buffers that duplicate memory per GPU, rather than using driver aliasing of the underlying resource.
* Ray tracing (hang): some buffer bindings weren't using a proper GPU index.
* Nanite (hang): Force initial clear of Nanite.MainAndPostNodesAndClusterBatchesBuffer to run on all GPUs. Solves GPU hang in shadow rendering the first frame (due to shadow rendering running across all GPUs), and later random hangs in view rendering.
* Distance field streaming (assert): GPU readback staging buffers need to be branched per GPU, as the underlying class is single device. GPU readback buffers and textures properly take into account the GPU they were last written on when locking and unlocking. Includes handling an edge case where a write can be queued when a lock is active, due to the deferred way commands are played back in the render graph.
* Distance field streaming (assert): UAV clear wasn't taking into account GPU index.
* GPU scene update needs to run across all GPUs.
* Fix for "DumpGPU" command to avoid assert with MGPU -- arbitrarily pick a GPU (last index) when the GPU mask contains multiple bits. Hope to improve this in the future, but it works.

Adds 20us to TSR's DilateVelocity, but eliminate MotionBlur's velocity flatten that is 120us on console.

Add static_assert to prevent the creation of new ones moving forward.
Used SHADER_PARAMETER_SCALAR_ARRAY/GET_SCALAR_ARRAY_ELEMENT for single parameters, or packed them with surrounding parameters when possible.

Now only r.AntiAliasingMethod prevails to selects the anti-aliasing method explicitly for the deferred shading renderer. Each AA technic have it's own cvars to control their quality independently
FXAA now have its own r.FXAA.Quality. The FXAA shader permutations where mis configured with r.PostProcessAAQuality=1 & 2 both mapping to the FXAA_PC_CONSOLE=1 that is now r.FXAA.Quality=0. Instead r.FXAA.Quality now offer more mid-quality settings for FXAA_PC=1 with r.FXAA.Quality=1 & 2 & 3. Backward comaptible migration is as followed:
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=0 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=1 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=2 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=3 -> r.FXAA.Quality=3 but with some neighborhood search setting changed in FXAAShader.usf
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=4 -> r.FXAA.Quality=4
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=5 -> r.FXAA.Quality=5
TAA now have its own r.TemporalAA.Quality. Backward compatible migration is as followed:
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=0 -> r.AntiAliasingMethod=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=1 -> r.AntiAliasingMethod=1 r.FXAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=2 -> r.AntiAliasingMethod=1 r.FXAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=3 r.TemporalAAUpsampleFiltered=0 -> r.TemporalAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=3 r.TemporalAAUpsampleFiltered=1 -> r.TemporalAA.Quality=1
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=4 -> r.TemporalAA.Quality=2
MSAA r.AntiAliasingMethod=3 & TSR r.AntiAliasingMethod=4 remains unchanged.
sg.AntiAliasingQuality now maps to different r.TemporalAA.Quality or r.FXAA.Quality
