[KV] Extract event reporting and remove traces

Created KeyValueBackupReporter, which includes:
* Logcat (main and event buffers).
* Backup observer.
* Backup manager monitor.

Also removed traces since they weren't very useful. Hopefully this will clear
KVBT of noise and help spot refactor opportunities. Did some small refactors
along w/ it.

Methods are starting to fit in one (big) screen :)
