Jiawei Shao 46513c7810 Add validation to the maximum inter-shader stage variable location 
This patch adds the validation rules on the maximum inter-shader
stage variable locations. According to Vulkan SPEC, "Each effective
Location must have a value less than the number of location avaiable for
the given interface", and according to Table 18 "Shader Input and Output
Locations", the number of available vertex output locations is
maxVertexOutputComponents / 4, and the number of available fragment input
locations is maxFragmentInputComponents / 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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
