Configure clang plugin to check raw pointers in containers

Configure Clang's raw-ptr-plugin to detect raw pointer types stored
inside container member fields (such as std::vector<T*>,
absl::flat_hash_set<T*>, etc.) to expand MiraclePtr coverage.

- Add clang_raw_ptr_plugin_config_file to default GN args pointing to //src/utils/raw_ptr_plugin_config.yaml.
- Add src/utils/raw_ptr_plugin_config.yaml defining included container types (base::flat_tree, std::vector, std::deque, std::set, absl::flat_hash_set, etc.).
- Update the clang_plugin template in src/utils/BUILD.gn to forward  inputs, cflags, and configs.
- Update raw_ptr_check in src/utils/BUILD.gn to pass config-path to the plugin when enable_check_container_fields is true, and register the config file as a target input.

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.
