Add validation rules for CopyTextureForBrowser

This CL complete the validation rules for CopyTextureForBrowser by:
 - Restrict source texture must have |CopySrc| and |Sampled| usage.
 - Restrict destinaton texture must have |CopyDst| and
   |RenderAttachment| usage.
 - Restrict sample counts of source texture and destination texture
   must be 1.
 - Restrict source copy origin.z must be 0.
 - Restrict CopyTextureForBrowser() can only copy to single slice.

A validation unittest is added to check.

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
