[Static samplers] Add ability to chain static sampler in binding layout

This CL adds the ability to chain a static sampler in a sampler binding
layout, as well as initial validation and testing of static samplers:
* They can be chained only if the relevant feature is enabled
* If a static sampler is chained, it must contain a valid sampler object

Nothing yet uses static samplers - that will be for followup CLs.

Followup work will also add validation of the sampler object against the
type specified in the sampler binding layout and tests of this
validation.

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.
