Yunchao He cb9b2f9fdd 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, a WebGPU implementation

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:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A "native" implementation of WebGPU using platforms' GPU APIs:
    • D3D12 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
