Partial MSAA expand-resolve

This adds a 'dawn_partial_load_resolve_texture' feature extending
'dawn_load_resolve_texture' to support partial MSAA expand-resolve.
'RenderPassDescriptorExpandResolveRect' can be chained into
'RenderPassDescriptor' to indicate that only the region of rect needs to
be expanded and resolved, so that we don't need to do that always
against the whole MSAA texture.

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.
