merge: add --quit

This allows to cancel the current merge without resetting worktree/index,
which is what --abort is for. Like other --quit(s), this is often used
when you forgot that you're in the middle of a merge and already
switched away, doing different things. By the time you've realized, you
can't even continue the merge anymore.

This also makes all in-progress commands, am, merge, rebase, revert and
cherry-pick, take all three --abort, --continue and --quit (bisect has a
different UI).
