90bc2efada RDG refactor to enable draining of work after issuing occlusion queries. 
- New Drain() method on FRDGBuilder; will flush all pending work.
 - Drained passes are not culled; resource lifetimes are extended; async compute fences are optimized as best as possible but fence joining may occur after the drain.
 - Batch up and pre-build all resource transitions. This is a prerequisite for parallel command lists.
 - Removed ServiceLocalQueue passes with built-in RDG AddDispatchHint().

d66076eacf Added RDG validation to check for dangling pointers and assert at AddPass time. Tracks resources actively used in the graph and will emit an assert if an incoming resource isn't part of the set. This would catch, for example, if the user kept around a resource from a previous builder and tried to reuse it in a new builder.

9fc8b1722d Refactored RDG ConvertToUntrackedX functionality into the RDG builder; renamed the operation to 'FinalizeAccess' for clarity, as the resource is considered finalized in the graph and will not transition to any other state. This operation now supports multiple resources, improving performance in cases where multiple resources are finalized back-to-back. Added validation to check that the user don't attempt to use it outside of its finalized state. Fixed up a few places where this assumption was being violated. Minor refactors in various places to use new API.

8c1793ad5a Integration of RHI transient allocator into RDG. 
- Replaced legacy transient support from RDG and replaced with new API.
 - Reworked acquire / discard operations a bit and added RHI validation to track correctness.
 - Reworked RDG barrier batching to include acquire / discard operations.
 - Hardened render pass merging logic and expanded to support lifetime extension of transient resources.
 - Added transient tag to RDG insights to track which resources are transient.

0d7dc4d4ed Refactor of uniform buffer binding to allow for runtime selection of static or per-shader binding. This is a necessary precursor to moving the View uniform buffer to use static bindings on mesh passes; it is used in so many places that both binding models are required to preserve compatibility. Added validation to catch when a uniform buffer is bound using both methods at the same time. Added CVar to RHI transition validation to control whether to break in the debugger on a transition failure.
