docs: add comments for nearly all tsconfig options in use

- since we can use comments in tsconfig.json, add them to give simple,
  one-liner explanations as to what each setting does
- also add a link to the TSConfig Reference for further details
- and specify which options are recommended as true by TS but not on by
  default for backwards compat or other reasons

- a few leftover that I still need to think about
