perf tui: Make <- exit menus too

In fact it is now added to the hot key list when newt_form__new is used,
allowing us to remove the explicit assignment in all its users.

The visible change is that <- will exit the menu that pops up when -> is
pressed (and Enter when callchains are not being used).
