Log mode changes to OP_RUN_ANY_IN_BACKGROUND

This app-op puts the app into background restriction and should only be
done via user-consent. Adding a temporary log to collect data about its
modifications.

Test: Manually put any app into "Restricted" mode under battery settings
and observe the logs.
Test: switch appops using the command `appops set` and observe the
logs.
