Bluetooth: host: Add calling of read_remote_version

Browse source 
Make remote features and remote version accesible to the application
through the bt_conn_get_remote_info object. The host will auto initiate
the procedures. If the procedures have not finished with the application
calls bt_conn_get_remote_info then EBUSY will be returned.
The procedures should finish during the first 10 connection intervals.
