D3D12: Use same format for null RTV in render pass and unused RTV in PSO

This patch uses same format (currently RGBA8Unorm) as the DXGI format
of both null RTV used in render pass and unused RTV when creating render
pipeline state object. Without this patch D3D12 debug layer will generate
below error message when we use a PSO that uses RTV at slot 1 and remain
empty at slot 0 in a D3D12 render pass:

The current render pass binds a different render target format compared
to what the pipeline state object describes. Render pass is predicted to
bind DXGI_FORMAT_R8G8B8A8_UNORM at [0], but PSO describes
DXGI_FORMAT_UNKNOWN at [0]. [ EXECUTION ERROR #1170: RENDER_PASS_ERROR]

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
