feat(rhi): refactor resource & barrier management for D3D12

Browse Source 
Modernizes resource and barrier management for the D3D12 backend. Key changes:
- Simplifies BarrierDesc by removing nullable "before" states; now inferred from resource database.
- Adds IsAliasing flag to BarrierDesc for aliasing transitions.
- Replaces ResourceMemoryType with HeapType in BufferDesc and related APIs.
- Enhances ResourceViewGroup with usage inference methods.
- Adds D3D12 utility helpers for heap/flag conversions and resource description extraction.
- Optimizes command buffer barrier emission, skipping redundant barriers.
- Refactors Material and RenderContext to use new APIs and state tracking.
- Updates ResourceManager pooling to use HeapType and standard Queue.
- Simplifies RenderGraphExecutor barrier logic and aliasing handling.
- Improves RenderSystem frame synchronization and resource retirement.
- Cleans up obsolete code and improves debug output.

BREAKING CHANGE: Updates to resource and barrier APIs require changes to all code interfacing with resource creation, barriers, and memory types.
