D3D11: add clear_color_with_draw toggle

D3D11 ClearRenderTargetView() could be buggy with some old driver
or GPUs. So add this toggle to force dawn using draw to clear
color attachments of a render pass.

This CL also fixes some issues in MaybeApplyClearWithDraw()
1. the draw quad's vertex coordinates are wrong.
2. the pipeline sample count doesn't match the render pass
3. the pipeline depth and stencil doesn't match the
   render pass.

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.
