refactor(profiles): bootstrap script
- Swap out the funcall+alist lookup for a pcase (which is expanded to a cond, which is is faster and easier to read). - Wrap bootstrap file to $EMACSDIR/profiles/init.el, but byte-compile it to $EMACSDIR/profiles/init.X.el where X is emacs-major-version. - Make doom-profiles-save's second argument optional (defaults to doom-profiles-bootstrap-file). - Make doom-profiles-save throw a error if byte-compilation fails for some reason. - Rename the tempvars to include 'doom' in their name, so debuggers know where they originate.
