- 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.
