Fix crash when accessibilityRole="tabbar" is used on Android

tabbar is part of the public AccessibilityRole union in both Flow and
TypeScript with nothing marking it iOS-only, but the Android enum had
no TABBAR entry, so fromValue() threw during createViewInstance and the
app crashed on mount.

Add TABBAR to the enum and map it to android.view.View, alongside TAB
and TABLIST which also have no dedicated Android widget.

Fixes #57890
