Add GitHub workflow for wasm-wasi-component

This adds a GitHub CI workflow for the new wasm-wasi-component language
module.

Some things of note.

1) We need to special case 'wasm-wasi-component' in the 'Output build
   metadata' section as we are splitting the module names on '-' to
   split them into name and version.

2) Apart from needing to tell bindgen about the njs include paths, we
   also need to explicitly specify which version of clang to use to
   work around an issue with multiple versions of clang installed.
