Major overhaul of resource barrier and state tracking in RenderGraph: - Introduce ResourceBarrierData for explicit (layout, access, sync) tracking. - Separate aliasing and transition barriers; explicit aliasing support. - Remove BufferHint; infer buffer usage from BufferUsage flags. - Update TextureAccess/BufferAccess to include usage requirements. - Improve enums (BarrierSync, BarrierAccess, BarrierLayout) for D3D12 alignment. - Update D3D12CommandBuffer to use new barrier data and error handling. - Make D3D12DescriptorHeap a class; add ReleaseSampler to IResourceDatabase. - Reset resource pools and aliasing managers each frame. - Batch and flush barriers efficiently per pass. - Update HLSL mesh shader macros to [NumThreads]. - Remove obsolete code and improve documentation. This refactor improves correctness, extensibility, and prepares for advanced features.
