remote: repack packed-refs once when deleting multiple refs
When 'git remote rm' or 'git remote prune' were used in a repository with many refs, and needed to delete many remote-tracking refs, a lot of time was spent deleting those refs since for each deleted ref, repack_without_refs() was called to rewrite packed-refs without just that deleted ref. To avoid this, call repack_without_refs() first to repack without all the refs that will be deleted, before calling delete_ref() to delete each one completely. The call to repack_without_ref() in delete_ref() then becomes a no-op, since packed-refs already won't contain any of the deleted refs.
