TeaVM Impl

[rosstroha]

Support for TeaVM JS Transpiling.

Many of the changes are related to the regexes. TeaVM does not support named groups, so the groups had to be switched to integer based references.

Would like to see a test along the lines of, a JS file which imports the resulting JS, runs the exported methods against a sample policy, and asserts on the resulting strings.

(This will require adding the setup-node action, which can hardcode 20 rather than bothering testing against multiple versions.)

@bakkot What if I did this as part of the csp validator website? I think someone mentioned combing the repositories so it might make sense to do that in the JS ecosystem instead of having to implement something here.
