Replace use of EventLogger in MR2ServiceImpl with Slog

Browse Source 
Logs that previously appeared in dumpsys now appear in
system logs.

For testing, get system logs live with logcat, for example:
adb logcat MR2ServiceImpl:I *:S
or generate a bug report, for example:
adb bugreport
then browse the file with the Android Bug Tool UI at
go/abt-web

Bug: 259705163
Test: manually
