Subject: [PATCH 03/19] use completionItem/resolve to fetch docs

- this makes completion faster because we defer fetching docs
    - we binary_to_term/encode the relevant data to put in the data
      which then gets sent back up on the resolve request
- also includes signature in docs
- makes cursor finding faster by skipping subtrees that don't contain
  the cursor position

code is still WIP, which is why its ugly

on average of typing around in the next_ls.ex file, completions seem to
be around 45-55ms. still not as fast as I'd like them, but still
decent-ish
