[dawn][native][emscripten] Move/rename bindingArraySize to core struct

The handling of the new struct is equivalent to the handling of the old
struct with an extension, so this is like the extension struct is always
on. Validation is updated so that instead of the extension struct being
unsafe, bindingArraySize > 1 is unsafe. (bindingArraySize = 0 and 1 are
equivalent, and both are allowed with both array and non-array shader
bindings).

If any dependencies use non-designated initializers to create
WGPUBindGroupLayoutEntry objects (like in WireArgumentTests.cpp), this
will break compilation. Fortunately there doesn't seem to be any build
breakage in Chromium or Skia.

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.
