cameraservice: Clean up tag monitoring output

Printing tag monitoring information either via `watch` or `dumpsys`
command had a few bugs. This CL fixes the following:

- Missing newline after "(Removed)" tags
- Move changes in input and output stream ids to its own line. Changes
  to stream ids and changes to tag values were coupled in outputs. After
  this CL, changes to stream ids show up in their own line regardless of
  any other tag changes.

Test: Manually tested using `adb shell cmd media.camera watch live`
