Build with bazel

It seems appropriate that a tool for bazel would also be built with bazel.

I did some work to convert the repository to use rules_nodejs https://github.com/zaucy/vscode-bazel/tree/build_with_bazel. It compiles, but I went over scope and changed too many other things. I could work on it further if there is interest.

I would definitely be interested in seeing a cleaned up version of how that would look! At the very least, it would be an improvement in the way we generate the protos we need.
