Add device record for BR/EDR devices with derived LE keys

Loads BLE keys stored in NVRAM to btm_sec database for BR/EDR
devices with cross transport derived LE keys after BT reset.
This change also makes sure that after BT reset, while loading
the bonded devices from NVRAM, the bonded devices(with device
type BR/EDR and having derived BLE keys) are also added to the
resolving list after loading the IRK into btm_sec database.
