Refactor Doom core & reload autoloads remotely

- Move subr-x/cl-lib loading to core-lib
- Revise docstrings for and rename various CLI functions to be more
  descriptive and up-to-date
- After regenerating autoloads file, bin/doom will try to reload
  autoloads files remotely, through the server/daemon, if possible. This
  is highly experimental and could break
