    frameworks: Add tunable for GlobalActions configuration

    Before, the power menu may have not updated when switching users.
    With tunables, we can be sure each user will only see their own settings.

    Remove the ACTION_UPDATE_POWER_MENU broadcast as well.

    GlobalActionsDialog: Remove broken PhoneStateListener for airplane mode toggle

    The Airplane Mode toggle in GlobalActions is completely broken,
    being stuck in TurningOn transition state when pressing it when
    Airplane Mode is off. This happens because the PhoneStateListener
    doesn't trigger onServiceStateChanged when Airplane Mode turns on.
    This commit removes the redundant PhoneStateListener and makes the
    logic work for Telephony and non-Telephony devices pretty much the
    same way by allowing onAirplaneModeChanged() to handle both cases.
