add new flight modes from ardupilot master

There are several flight modes which need to be added:

Plane is currently:
// @Values: 0:Manual,1:CIRCLE,2:STABILIZE,3:TRAINING,4:ACRO,5:FBWA,6:FBWB,7:CRUISE,8:AUTOTUNE,10:Auto,11:RTL,12:Loiter,14:AVOID_ADSB,15:Guided,17:QSTABILIZE,18:QHOVER,19:QLOITER,20:QLAND,21:QRTL

Of note, AVOID_ADSB and Q\* were added recently.

and copter is:
// @Values: 0:Stabilize,1:Acro,2:AltHold,3:Auto,4:Guided,5:Loiter,6:RTL,7:Circle,9:Land,11:Drift,13:Sport,14:Flip,15:AutoTune,16:PosHold,17:Brake,18:Throw,19:Avoid_ADSB,20:Guided_NoGPS

Of note, AVOID_ADSB was added recently.

No file or test is named. Compare Mission Planner's Plane and Copter flight-mode definitions with the ArduPilot master values listed in the issue, then identify the entry point that supplies those modes to the UI. Done means the listed AVOID_ADSB and Q* modes are recognized and displayed correctly for the appropriate vehicle types.
