Metal: Support larger maxInterStageShader limits

This patch adds the support of larger maxInterStageShaderVariables
and maxInterStageShaderComponents on Metal.

On Apple silicons:
- maxInterStageShaderVariables = "Inputs to a fragment function"
  (range from 60 to 124)
- maxInterStageShaderComponents = "Input components to a fragment
  function" (124)

On non-Apple silicons:
- maxInterStageShaderVariables = "Inputs to a fragment function" - 4
  (every built-in variable will consume an individual inter-stage
  shader variable according to the experiments)
- maxInterStageShaderComponents = maxInterStageShaderVariables * 4

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
