Add event log for uid state tracker in dumpsys

This adds more debugging data for changes in uid state and results when
modes are evaluated against their uid states. The parameters increase
the total memory usage of AppOpsService by about 1% by adding about 9kb
of usage.

Test: Manual + check memory usage in heapdump
