wifi: nl80211/cfg80211: support operating as RSTA in PMSR FTM request

Add an option to operate as the RSTA in an FTM measurement request.
When requested, the device will dwell on the requested channel until
the peer starts the FTM negotiation. This option is only valid for
trigger-based/non trigger-based measurement with LMR feedback which
will allow the RSTA to receive the results of the measurement.
