ui/cocoa: Do not use console_select()

ui/cocoa needs to update the UI info and reset the keyboard state
tracker when switching the console, or the new console will see the
stale UI info or keyboard state. Previously, updating the UI info was
done with cocoa_switch(), but it is meant to be called when the surface
is being replaced, and may be called even when not switching the
console. ui/cocoa never reset the keyboard state, which resulted in
stuck keys.

Add ui/cocoa's own implementation of console_select(), which updates the
UI info and resets the keyboard state tracker.
