android: Allow opening in-emulation menu by pressing Back (#6248) 

It seems like the menu isn't showing up for users on Android 13.
We're not sure what's wrong, and the approach we've been using for the
menu hasn't been entirely reliable in the past either (in particular
not on non-mobile form factors like Chromebooks and VR devices),
so let's make it possible to open the menu by pressing Back,
an action that works reliably on most kinds of Android devices.
(Not sure if there's an equivalent of Back on devices like watches,
but I think we can pretty safely ignore those for now.)
