Implement readonly depth/stencil attachment on D3D12
This change adds a end2end test for readonly depth/stencil
attachment and implements it on D3D12.
This change focuses on depth. If it is OK, I will add test(s) for
stencil.
The key points are:
- Set DEPTH_READ transition barrier to replace DEPTH_WRITE barrier
if it is readonly depth/stencil attachment.
- Set appropriate D3D12_DEPTH_STENCIL_DESC (which is already correct)
and D3D12_DEPTH_STENCIL_VIEW_DESC (which needs some particular
flags). Otherwise, the underlying driver (validation layer) may
think we still need DEPTH_WRITE transition barrier.

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
