Commander: Introduce global_position_relaxed (#24280)

To separate accuracy requirements for VTOL hover and cruise.

- global_position_relaxed refers to having a valid horizontal velocity aid source 
in the estimator and a set global reference position, but poses no requirements 
on the accuracy of the provided position estimate. 
- Auto flight modes Mission, Loiter and RTL, while in fixed-wing mode, 
only require the relaxed global position going forward
- COM_POS_FS_EPH is thus no longer used on fixed-wing vehicles (resp. VTOL in FW)
- rename failsafe_flags.local_position_accuracy_low to failsafe_flags.position_accuracy_low
