[utils] Re-enable -Wunsafe-buffer-usage, add tests

Accidentally disabled when setting up -Weverything, because it triggered
on Wasm tests.

- Fix the Wasm tests.
  - Note the unsafe buffers plugin isn't enabled for Wasm builds, so the
    `-third_party/` suppression in unsafe_buffers_paths.txt doesn't
    apply, but we still get the warnings via -Weverything.
  - DAWN_UNSAFE_TODO is used instead of DAWN_UNSAFE_BUFFERS because we
    want to switch these to spanified APIs soon.
- Re-enable the warning.
- Add nocompile tests for basic builtin stuff, and for Dawn types that
  use DAWN_UNSAFE_BUFFER_USAGE.

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.
