Enable RC calibration mode during RC calibration to tell vehicle to ignore stick inputs for that period

Altitude splitted to altitudeAMSL and altitudeRelative, speed splitted to airSpeed and groundSpeed. PrimaryFlightDisplay uses airSpeed for FW and groundSpeed for MC.

Fixed Compiler Error C2864 - only static const integral data members can be initialized within a class
