hostapd: Add a configuration to set an AP as stationary

Add a configuration option in hostapd.conf and in neighbor report that
sets an AP as stationary. To enable this option on the current AP set
the config option stationary_ap to 1. To set a neighbor entry to be
marked as stationary add the word stat to the SET_NEIGHBOR command. This
option tells hostapd to send LCI data even if it is older than requested
by max age subelement in RRM request.
