custom-file = ~/.doom.d/config.el

custom-file is now set to your private config.el, because users may want
to be able to see what Customize is storing (and where) front and
center. Storing it away in ~/.emacs.d/.local makes it harder to notice.

Also, have enable-command (and disable-command) save their data to
custom-file instead of ~/.emacs.d (see #3379).

Fixes #3379
