Revert "D3D12: Stage BindGroups on CPU descriptor heaps."

Browse Source 
This reverts commit 2479860e4b.

Reason for revert: Causes WebGPU CTS failures

Original change's description:
> D3D12: Stage BindGroups on CPU descriptor heaps.
> 
> Instead of directly populating GPU heaps, pre-encoded
> BindGroups are staged on CPU heaps then copied over
> to the GPU. Non-shader visible allocators are stored
> on the BGL, which hands out fixed-size chunks to
> simplify memory managment. To enable memory re-use,
> CPU allocations are tied to the lifetime of BindGroup
> objects.
