refactor(config-utilities): extract cj/--recompile-emacs-home

Splits the delete-then-recompile work out of cj/recompile-emacs-home
so it takes DIR and an explicit NATIVE-P flag instead of probing
boundp inside the work loop. Returns 'native or 'byte to surface
which path actually ran.

The interactive wrapper still asks `yes-or-no-p' against
user-emacs-directory and probes `(boundp 'native-compile-async)' once
to decide the dispatch and the prompt's wording. The cancellation
message is unchanged.
