Support overflow items with 'More' button in BottomNavigation.

Is your feature request related to a problem? Please describe.
When using the BottomNavigation as the main menu in a React Native application, it's currently not possible to add too many items.

Describe the solution you'd like
I would like to propose an enhancement to the BottomNavigation component that allows developers to set a maximum number of visible items. Any additional items beyond this limit would be grouped under a "More" button. When the user clicks on the "More" button, the extra items would be displayed in a submenu.

Additional context
In my current React Native Expo project, the main menu is built using BottomNavigation. There is a requirement to display many sections in the menu, and having a clean and organized way to show all necessary items is crucial for usability.
