[bazel] Add explicit rules_cc loads

Dawn's Bazel support is narrow and still experimental, but Bazel
is flexible enough that Dawn can still be integrated into larger
Bazel setups.

The generated Bazel files, along with a few handwritten ones,
were not Bazel 9 compatible. Bazel no longer provides these C++
rules as builtins, and now requires explicit loads from rule
repositories such as rules_cc.

Fix this by adding load statements from rules_cc at each usage
site. This updates the generator template and regenerates the
affected BUILD.bazel files.

Tested with Bazel 7.x and 8.x in WORKSPACE mode. Bazel 9 testing
was not attempted because WORKSPACE mode has been removed there.

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.
