D3D11: Implement Pixel Local Storage

This patch implements Pixel Local Storage (PLS) on D3D11 backends.
- The PLS UAVs are always allocated at the end of all RTV and UAV
  slots when creating the render pipeline.
- The PLS UAVs are treated as fixed UAVs in BindGroupTracker and
  will always be set together with other UAVs in BindGroups. The
  the UAV slots in OMSetRenderTargetsAndUnorderedAccessViews() are
  allocated as below:
  (RTVs) , null, null, ..., UAVs-from-bindgroups, UAVs-for-PLS
- Internal texture views are created to implement implicit PLS.

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.
