dawn::native: Implement wgslLanguageFeatures.

Adds support for Instance::HasWGSLLanguageFeature and
Instance::EnumerateWGSLLanguageFeatures based on the data provided by
Tint in src/tint/lang/wgsl/features/status.h. A toggle is added to (by
default) hide the "chromium_testing_*" language features.

Use these testing features in a unittests.

Make the device use the instance's list of enabled language features to
pass the AllowedWGSLFeatures to Tint's WGSL reader.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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, 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.
