In 939b7bfe66 we synced up the NSMenuItem's
title to that of the corresponding NSMenu, as AppKit was observed to use
the NSMenuItem title for its heuristics of when to add dictation and
emoji entries to the menu.
But AppKit's heuristics are based on the localized name of the edit menu,
so we need to follow suit and look up AppKit's own localizations. This
is of course fragile, as we're relying on this localization continuing
to live in the InputManager table, but if that changes we'll just fall
back to using the title from the NSMenu, as we did before.
In addition, AppKit's heuristics also look for menu items in the menu
that match selectors such as copy:, paste:, etc, so even if our lookup
of the localized title fails, the additional heuristics would in most
cases still succeed in detecting the edit menu.
