Update depth-stencil copy validation

Depth/stencil copies of partial subresources is disallowed in
WebGPU because this is a D3D12 restriction. This restriction
need also to be enforced on B2T, T2B and WriteTexture.

This CL also fixes the subresource whole size calucation to use
the mip level. Previously, the 0th level size was always used.

This CL updates the validation to be correct and adds tests.
The DepthStencilCopy tests are factored into smaller helpers to
reduce code duplication.

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
