[BottomNavigationView] BottomNavigationView can have only one setOnNavigationItemSelectedListener

FEATURE REQUEST

As per title, BottomNavigationView can have only one setOnNavigationItemSelectedListener. This is annoying because if i use the
bottomNavigationView.setupWithNavController(navController)
this internally sets that listener, and i cannot use it anymore for anything else (like setting the text in a custom appBar, for example)
A list of listeners would be the right thing in my opinion.

Ps. this probably applies to setOnNavigationItemReselectedListener(BottomNavigationView.OnNavigationItemReselectedListener listener)
too.

For Pattern reference, see NavController addOnDestinationChangedListener and removeOnDestinationChangedListener

Beginne damit, die APIs BottomNavigationView's setOnNavigationItemSelectedListener und setOnNavigationItemReselectedListener zu lesen, und vergleiche dann ihr Verhalten mit dem Muster aus NavController's addOnDestinationChangedListener und removeOnDestinationChangedListener. Die Umsetzung sollte es der Navigationskonfiguration und einem weiteren Consumer ermöglichen, die relevanten Callbacks zu empfangen, ohne das Verhalten bestehender Listener zu beeinträchtigen.
