ADSB traffic avoidance improvements using UTM_GLOBAL_POSITION (#13159)

* Treat UAVS diffrently from manned aviation 
 * Added fake_traffic testing functionality,
 * Added NAV_TRAFF_AVOID Hold and Landmode
 * Added Behavior: HOLD Position to collision avoidance mode and implemented Landmode to collision avoidance.

Boards where no Hardware GUID is defined will send 0 as GUID.

Right now collision avoidance for more than one FMU without Hardware GUID is not possible.
We should consider adding a randomly generated HW GUID as a placeholder for legacy Boards
