BLE: Update APIs to take advantage of ble::peer_address_type_t

Deprecation:

* Gap::AdvertisementCallback::addressType has been deprecated in favor of Gap::AdvertisementCallback::peerAddrType.
* Gap::ConnectionCallbackParams::peerAddrType has been deprecated in favor of Gap::ConnectionCallbackParams::peerAddressType.
* Gap::ConnectionCallbackParams::ownAddr has been deprecated in favor of nothing else as this information may be not available.

Overloads added to accept a peer_address_t:

* Gap::connect
* Gap::processConnectionEvent
* Gap::processAdvertisingReport
