dawn::wire Support wgslLanguageFeatures

In addition to adding support for wgslLanguageFeatures in the wire, this
CL does the following:

 - Add a wgpu::DawnWireWGSLControl structure to control what is exposed
   in wgslLanguageFeatures in the wire.
 - Updates WireClient::ReserveInstance to pass a WGPUInstanceDescriptor
   so that the wgsl control info can be passed to
   dawn::wire::Instance::Initialize.
 - Update the WGSLFeatureValidationTests to enable them on the wire.
 - This requires creating a new wire instance with a matching native
   instance for the shader module compilation tests, so add a helper
   method to WireHelper (so much helping!!) that creates an instance
   from both a native and wire InstanceDescriptor.

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.
