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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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
