iOS: filter first responder actions from edit menu

Browse Source 
UIResponderStandardEditActions found in first responder will be prepended to
the edit menu automatically (or e.g made available as buttons on the virtual
keyboard). So we filter them out to avoid duplicates, and let first responder
handle the actions instead. In case of QIOSTextResponder, edit actions will be
converted to key events that ends up triggering the shortcuts of the filtered
menu items.
