Allow userspace to enable fine timing measurement responder
functionality with configurable lci/civic parameters in AP mode.
This can be done at AP start or changing beacon parameters.
A new EXT_FEATURE flag is introduced for drivers to advertise
the capability.
Also nl80211 API support for retrieving statistics is added.

v5:
- changed NL80211_ATTR_FTM_RESPONDER to nested attr type
- renamed 'civic' param to 'civicloc'
v4:
- no changes
v3:
- fixed ftm responder disabled case to be not supported.
- changed ftm_responder param from bool to s8.
