webgpu.h: More trivial defaulting: BindGroupLayoutDescriptor

Implements the following sub-structures of BindGroupLayoutDescriptor.
Defaulting is done in the constructor, which (in most cases) is called
by a bounce through the backend.

- TextureBindingLayout.viewDimension: TextureViewDimension = 2D
- StorageTextureBindingLayout.viewDimension: TextureViewDimension = 2D

I couldn't find any end2end tests using explicit bind group layouts with
texture or storageTexture, so these are only spot-tested in the
GetBindGroupLayout caching tests (which won't hit the backends but will
verify that defaulting is applied to cache keys).

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.
