webgpu.h: Re-number enums, with defaulting: SamplerDescriptor

Trivial defaulting (matching what's defined in the upstream WebIDL) is
done via a new method .ApplyTrivialFrontendDefaults() called in various
places in the frontend as needed.

Part 1 implements the following, which occur directly in CreateSampler:

- SamplerDescriptor.addressMode[UVW]: AddressMode = ClampToEdge
- SamplerDescriptor.{min,mag}Filter: FilterMode = Nearest
- SamplerDescriptor.mipmapFilter: MipmapFilterMode = Nearest

Spot tests are added for all of these. They won't necessarily catch if
the defaulting is _wrong_, but should crash if it is _missing_.

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.
