- New RHI command list SetTrackedAccess method for the user to supply a current whole-resource state.
- New RHI command context GetTrackedAccess method for querying the tracked access in RHIBeginTransitions / RHIEndTransitions on the RHI thread.
- Hooked RHICmdList.Transition and FRHICommandListExecutor::Transition to assign tracked state automatically.
- Refactored RDG and resource pools to use new RHI tracking.
- FRDGPooledBuffer / FRDGPooledTexture no longer contain tracked state. RDG temp-allocates state through the graph allocator instead.
- All prologue transitions are 'Unknown', and all epilogue transitions coalesce into a whole resource state.
- Implemented platform support for patching the 'before' state with the tracked state.
- Implemented various RHI validation checks:
- Asserts that the user assigned tracked state matches RHI validation tracked state, for all subresources.
- Asserts that tracked state is not assigned or queried from a parallel translation context.
- Added FRHIViewableResource and FRHIView base classes to RHI. FRHIView contains a pointer to an FRHIViewableResource. This is currently a raw pointer, but should be extended to a full reference in a later CL.
NOTE on RHI thread constraint:
Transition evaluation is now restricted to the RHI thread (i.e. no parallel translation contexts). Transitions aren't performed in parallel translate contexts anyway, so this is not a problem. If, however, we decide to refactor parallel translation to be more general, this implementation could be extended to track the state per context and update from the 'dispatch' thread.

This change is the copy-up of work from //UE5/Dev-ParallelRendering to unify the various RHI texture types
- The separate RHI texture types (FRHITexture2D, FRHITexture2DArray, FRHITexture3D, FRHITextureCube, FRHITextureCubeArray) have been replaced with a single type: FRHITexture.
- Includes the required refactoring / fixes for the various platform RHIs.
The old texture types are still supported via typedefs, but will soon be marked deprecated. Future rendering code should make use of the FRHITexture type instead.

rhi.DumpResourceMemory dumps the memory usage of each RHI resource if the type is instrumented. Currently only fully implemented for Textures and Buffers in D3D11 and D3D12.
rhi.DumpResourceCounts dumps the counts of each resource type. Should work for all RHIs.
Repurposed FRHIResourceInfo to use for generic resource info. Removed older uses of it that didn't actually provide data.
Made ERHIResourceType required to construct an FRHIResource.
Adding Name to FRHIBuffer.
Removed the unused FVulkanBuffer.
Removed the unused FOpenGLTexture and FOpenGLBaseTexture.

Changed water to use typed buffers instead of StructuredBuffers, as MALI GPUs do not support access to StructuredBuffers in a vertex shaders
