Corentin Wallez 20a6ca0041 generator_lib.py: Fix exception when racing for dir creation.
The generator_lib.py processing of file renders would check that the
output directory doesn't exist and if needed, would create it. However
by default makedirs errors if the path already exists. This caused
issues when multiple generator_lib.py generators with the same output
dir would run in parallel in builds, because there can be a race where:

 - GeneratorA: Check os.path.exists -> returns False
 - GeneratorB: Check os.path.exists -> returns False
 - GeneratorB: os.makedirs -> Ok
 - GeneratorA: os.makedirs -> Exception, fails the build.

Instead use os.makedirs(exist_ok=True) inconditionally to remove this
racy behavior.

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.
