This change adds support for running XR projects built with the `d3d12` rendering backend. The XR backend hooks into the setup for the D3D12 render context in order to use the desired device and command queue for submission to OpenXR. The XR backend takes care of importing the D3D12 swapchain images into the render context. As part of this process, three issues are addressed: - Ensuring that resource state transitions are only done on textures that require them. - Enabling view instancing in the PSOs for multiview render passes. - Addressing a bug in the D3D12 runtime where PSO creation may fail when front face detection is used. Please refer to #86283 for additional discussions on the implementation details.
