component/bt: add a option to make report adv data and scan response individually

Originally, when doing BLE active scan, Bluedroid will not report adv to
application layer until receive scan response. This option is used to
disable the behavior. When enable this option, Bluedroid will report
adv data or scan response to application layer immediately.
