wpa_supplicant: Allow FTM functionality to be published
Add configuration options that control publishing of fine timing measurement (FTM) responder and initiator functionality via bits 70, 71 of Extended Capabilities element. Typically, FTM functionality is controlled by a location framework outside wpa_supplicant. When framework is activated, it will use wpa_supplicant to configure the STA/AP to publish the FTM functionality. See IEEE P802.11-REVmc/D7.0, 9.4.2.27.
