- RHICreate{Vertex, Index, Structured}Buffer
- RHICreate{ShaderResource, UnorderedAccess}View
- RHIUpdateUniformBuffer
- Various initialization / locking methods for helper buffer types in RHIUtilities.h
The goal is to continue to force resource creation through command lists to avoid surprises with moving things off the render thread.

- Renaming GRHIGlobals.CurrentTextureMemorySize to GRHIGlobals.StreamingTextureMemorySizeInKB
- Renaming GRHIGlobals.CurrentRendertargetMemorySize to GRHIGlobals.NonStreamingTextureMemorySizeInKB
- Adding GRHIGlobals.BufferMemorySize and GRHIGlobals.UniformBufferMemorySize
- Deduplicating RHI stat accounting code and changing it to use RHI Descs.
- UE::RHICore::UpdateGlobalTextureStats is for StreamingTextureMemorySizeInKB and NonStreamingTextureMemorySizeInKB. This still allows platforms to control where the memory is counted.
- Adding more Buffer RHI stat accounting code to RHIs that were missing it.
- UE::RHICore::UpdateGlobalBufferStats is for BufferMemorySize and UniformBufferMemorySize.
- FillBaselineTextureMemoryStats initializes and fills the common members of FTextureMemoryStats.
- Adding ETextureCreateFlags::ForceIntoNonStreamingMemoryTracking which will force the texture to be counted in NonStreamingTextureMemorySizeInKB.
- Changing all RenderTargetPool textures to be flagged with ETextureCreateFlags::ForceIntoNonStreamingMemoryTracking so they aren't counted against streaming budgets.
- Adding UAV Texture stats instead of lumping them with regular textures
- Adding Buffer stats for ByteAddressBuffer, DrawIndirect and Misc

Also rename AssetName to OwnerName to better describe what is stored.

- Added resource pool counters and events.
- Added AllocatePooledBuffer method and refactored pool to no longer take a command list.
- Refactored swap chain barrier logic to be a bit cleaner.
- Added helper methods to cast between views.
- Added power of two alignment option to buffer pool.
- Added GetTypeHash implementations for RDG SRV | UAV descriptors.

- 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.

- 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.
