feat(tests): Add tests for taskbar recreation on nav bar state change
Adds unit tests to `TaskbarManagerTest` to verify that the taskbar is correctly created or destroyed when the `SYSUI_STATE_NAVIGATION_BAR_DISABLED` flag changes.
This covers the logic in `isTaskbarEnabled` and its callers (`recreateTaskbarForDisplay`, `onSystemUiFlagsChanged`) which determine the taskbar's lifecycle based on this system UI flag.
Tests are added for both the primary display and connected displays to ensure consistent behavior.
Add additional test coverage for ag/ based on change: ag/34296463.
