wifi: cfg80211: extend PMSR FTM response for proximity ranging

Browse Source 
Applications need negotiated session parameters to interpret
proximity ranging results and perform post-processing. Currently,
the FTM response lacks LTF repetition counts, time constraints,
spatial stream configuration, and availability window parameters.

Extend the FTM response structure to report these negotiated
parameters, enabling applications to track session configuration
and use them in post-processing to increase ranging precision.
