MAVExplorer: Update lookups for EV & ERR messages

Lookups for subsystems and events aligned to AP_Logger.h.

Reworked lookup table for subsystem-specific codes, so that they can be displayed.
Some have specific messages, some need to continue to display number (EKF_PRIMARY,
FLIGHT_MODE, FAILSAFE_FENCE), and others use generic codes.
