Closes#469
This PR adds a github workflow that is triggered by updates to the
`kernel/` directory or `runtime/src/extism-kernel.wasm` - it builds the
kernel, including using `wasm-strip` and makes a PR against any PR that
has a kernel module that doesn't match the expected output.
I had considered making this run when the PR is merged into main, but
this approach gives us a chance to run CI with the generated wasm file.
I think automatically adding a commit would be simpler, but this way
seems more transparent.
