D3D12: Add Screenshot wrapper overload and document known limitations

Browse Source 
- Add D3D12Screenshot::Capture(D3D12Device&, D3D12CommandQueue&, D3D12Texture&, const char*) wrapper overload
- Update minimal integration test to use encapsulated APIs
- Add DescriptorHeap wrapper unit tests
- Document minimal GetBuffer native call as known limitation in TEST_SPEC.md
