Logs hearing aid information when a hearing aid is bonded(connected) 

The information including device mode, device side, and entry page id where binding process starts. We only log the info once after the hearing aid is bonded. Without forgetting the bluetooth device, it won't log the info again if you disconnect and then reconnect it.

Bug: 237344016
Test: m statsd_testdrive & statsd_testdrive 490
