[dawn][native] Support BG with BGLs that use arraySize.

This expands the single BGL entry at the API surface into one
BindingInfo per element in the BGL's internal format. This lets BG
validation and code to store element unchanged. A test is added that one
must specify all the array elements when creating a BG with a BGL that
uses arraySize.

BGL validation is updated to require that elements created for the
arrays never go past maxBindingsPerBindGroup, and a test is added.

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.
