[tint] Wrap accessing argc & argv to remove suppressions

This adds in an utility for converting argc & argv passed into main()
into a tint::Vector of the arguments.

This is done because it is a known issue that accessing the c-style
argv will always cause `-Wunsafe-buffer-usage` to fire, and this
wrapper isolates this known needed suppression into a single location
instead of being scattered across the code base.

This CL cleans up a bunch of main.cc files using this new utility,
though there is a couple exceptions. In remote_compile/main.cc the
suppression is just narrowed, since there is non-main related issues
in that file. There are some other main.cc files, like for the
benchmark tool, that use a different broader suppression that are not
touched.

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.
