[dawn][native] Factor the logic to compute the tint::Bindings

This option passed to Tint compilation is used to remap bindings from
WGSL bind points, to whatever the backend needs to match how it sets
BindGroups. The logic in all backends look extremely similar apart from
how they map a (group, index) to a tint::BindPoint.

The logic is extracted in a GenerateBindingRemapping helper function in
TintUtils that takes a backend-specified functor for the mapping of a
(group, index) to a tint::BindPoint.

In the Vulkan backend, some leftover logic for static samplers is
extracted from the generation of the tint::Bindings to modify it a
posteriori.

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.
