Remove COM_POSCTL_NAVL

Browse Source 
In an effort to reduce configuration space.
I've not seen use for this option.
If a pilot flies manually in position mode he has some visual reference of the vehicle and can do better than an autonomous mode without position reference.
Also by now we have nudging in Descend mode so the pilot can still give input and the only difference is it automatically goes down instead of the pilot having to descend by stick to land.

### Position Loss Failsafe Action
The failure action is controlled by [COM_POSCTL_NAVL](../advanced_config/parameter_reference.md#COM_POSCTL_NAVL), based on whether RC control is assumed to be available (and altitude information):
- `0`: Remote control available.
Switch to _Altitude mode_ if a height estimate is available, otherwise _Stabilized mode_.
- `1`: Remote control _not_ available.
Switch to _Descend mode_ if a height estimate is available, otherwise enter flight termination.
_Descend mode_ is a landing mode that does not require a position estimate.
Fixed-wing planes, and VTOLs not configured to land in hover ([NAV_FORCE_VT](../advanced_config/parameter_reference.md#NAV_FORCE_VT)), have a parameter ([FW_GPSF_LT](../advanced_config/parameter_reference.md#FW_GPSF_LT)) that defines how long they will loiter (circle with a constant roll angle ([FW_GPSF_R](../advanced_config/parameter_reference.md#FW_GPSF_R)) at the current altitude) after losing position before attempting to land.
If VTOLs have are configured to switch to hover for landing ([NAV_FORCE_VT](../advanced_config/parameter_reference.md#NAV_FORCE_VT)) then they will first transition and then descend.
