hostapd: add FTM responder support

This adds support for enabling the FTM responder flag for the APs
extended capabilities. On supported hardware, enabling the ftm_responder
config key for a given AP will enable the FTM responder bit.

FTM support itself is unconditionally implemented in the devices
firmware (ath10k 2nd generation with 3.2.1.1 firmware). There's
currently no softmac implementation.

Also allow to configure LCI and civic location information which can be
transmitted to a FTM initiator.
