Prevent double touch inputs in the BaseDragLayer

If you hold a long press and while pressing you start another
long press again with another finger, then a new onLongPress event
will trigger and in some cases we are not processing that case.

By ignoring the evetns with the flag ACTION_OUTSIDE we can prevent
such cases.
