CMake-only fork of https://dawn.googlesource.com/dawn with cleaned, vendored dependencies

Unused aspects of depth-stencil attachments that are tagged as read-only used to leak that read-only state to backends, even if the validation made it seems like they always match (they only need to match if the texture has both aspects). This confused backends like Vulkan which checked for depthReadOnly || stencilReadOnly to choose between code paths. Instead reyify the depthStencilAttachement descriptor in the frontend to protect against garbage values being passed for aspects that aren't present in the texture. Adds a regression test, with the caveat that a failure is only shown by having the VVL output and error in stderr due to an unrelated issue.

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, 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.
