[infra] Cleanup/modernize PRESUBMIT.py

Since I am working on adding a new check to this file, decided to do
some housekeeping beforehand.

Added some missing documentation to functions.

Switched over to using the '2.0.0' version of the presubmit infra,
which means that functions of the form CheckXXX are automatically run
on commit and upload, so don't need to be explicitly called. So the
'common' check function can just be the canned check that are desired.

Used list comprehensions, and more modern iteration options to make
some of the code more terse.

Intentionally avoided using comprehensions in some places with nested
iterations, since though technically feasible to do, it makes very
unreadable code.

Confirmed that the file only used features available in 3.8. From what
I can tell depot_tools ships/uses 3.11, though I have previously seen
issues with bots only having 3.9 available.

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.
