KAP140: annunciate modes from per-mode status datarefs (same bitfield fix)

Browse Source 
The steam-panel KAP140 LCD decoded the same unreliable autopilot_state bitfield
as the G1000 panel, so its lateral/vertical annunciation could be wrong. Read the
*_status datarefs instead, consistent with AutopilotPanel and the PFD.
