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

- Cleanup is necessary because otherwise encoded render commands may be leaked if the validation encoding fails. (The leaked render commands can then trigger an assert in ~Device::Cache because the commands can hold a ref to an AttachmentState that was not destroyed, and hence still be in the device cache. - Added explicit check in EncoderIndirectDrawValidationCommands for device 'alive-ness' since it may create new objects later and hit the same error later on anyways. - Added regression test.

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.
