refactor(napi/parser): move JS code into src-js directory (#13899)

Pure refactor. Root of `napi/parser` was getting really crowded with tons of files, and I'm about to add a load more for the ESTree walker.

Move JS source files into a `src-js` directory, like in `apps/oxlint`, so that the root of the package is just config files and scripts.
