RRM: Add AP mode minimal advertisement support for testing 

The new hostapd.conf radio_measurements parameter can now be used to
configure a test build to advertise support for radio measurements with
neighbor report enabled. There is no real functionality that would
actually process the request, i.e., this only for the purpose of minimal
STA side testing for now.
