[dawn][native] Remove BGL::GetBindingIndex(BindingNumber)

BindingNumbers only make sense to convert to APIBindingIndex since
that's the integer type used to represent packed bindings that match
user-facing bindings.

One use of GetBindingIndex in the GL backend is only for sampled
textures and can be replaced with AsBindingIndex(GetAPIBindingIndex).

The other use of GetBindingIndex was in the Vulkan backend to convert
the BindingNumber in StaticSamplerBindingInfo::sampledTextureBinding to
a BindingIndex. In this CL that member is replaced with a BindingIndex
in the same BGL, which requires updating the StaticSamplerBindingInfo
after the reordering of bindings in the BGL creation, and updates to the
BindGroup validation code.

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.
