 - GAP: request role change for classic connection via `gap_request_role`
 - GAP: LE Whitelist API with 'gap_le_whitelist_x' with x = add, remove, clear and new `gap_connect_with_whitelist`
 - SDP Client: add sdp_client_register_query_callback() allows to register query request instead of polling sdp_client_ready()

 ### Changed
 - GAP: treat AES-CCM encrypted connection as mutually authenticated (BIAS)
