wifi: cfg80211: add ingress/egress distance thresholds for FTM

Browse Source 
Proximity detection applications need to receive measurement results
only when devices cross specific distance boundaries to avoid
unnecessary host wakeups and reduce power consumption.

Introduce configurable distance-based reporting thresholds that
drivers can use to implement selective result reporting. Add ingress
and egress distance parameters allowing applications to specify when
results should be reported as peers cross these boundaries.
