Fix CMake dependencies after the touch of generated files.

The empty placeholder files for generated files could have an access
time newer than all of their dependencies and not be generated. Fix this
by touching the generator script after creating the placeholder file.

The switch to interface libraries was using INTERFACE sources which made
CMake assume it could generate the files whenever, make them PUBLIC
instead so that the files are generated before any target using the
DawnJSONGenerator target.

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.
