LSP: A bunch of new OpenGOAL language features (#3437)

- Integrate the AST into the LSP, this makes parsing and tokenizing the
files much easier
- Consolidate most of the symbol info tracking in `goalc` to a single
map. Fixed some issues where the old map would never evict symbols when
re-compiling files. There is still some more to cleanup, but this now
can be used as an incrementally updated source-of-truth for the LSP
- re-compile files when they are saved. Ideally this would be done
everytime they are changed but that:
  - may be too aggressive
- goalc doesn't compile incrementally yet so it likely would be a worse
UX
