Jiawei Shao 60d6d0acd6 Add regression test for the Intel D3D12 driver bug about T2T copy
This patch adds a regression test to dawn_end2end_tests for an
Intel D3D12 driver bug about the T2T copies with specific texture
formats when the source mipmap level is greater than 0.

This patch also does several clean-ups in CopyTests.cpp to support
testing arbitrary texture formats:
1. Initialize the source textures with device.WriteTexture().
2. Set default values for TextureSpec.copyLevel (0),
   TextureSpec.levelCount (1) and TextureSpec.copyOrigin ({0, 0, 0}).
3. Add TextureSpec.format and set the default value for it (RGBA8Unorm).
4. Support initializing and comparing the texture data with arbitrary
   texture format instead of RGBA8Unorm only in CopyTests_T2T.
5. Check all the texels in the related destination texture subresources
   instead of only the copied texels.

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
