audiopolicy: Improve logging for device connection cases

Add meaningful profile names, while opening input and output profiles
on device connection.

Add logs in openDirectOutput method to get info in case existing
output is closed because of direct track repriorization, profiles are
found or not.

Add logs in setDeviceConnectionState for input device as well.
Add successful connection logs once setDeviceConnectionState completes.

Flag: EXEMPT bugfix
Bug: 345692843

      profile opening
