[SB Refactor] Remove non-mobile usages of MobileInputLogger.

Also removes the `logInputChange` and `logOutputChange` methods, since
now all logs to this logger are, by definition, input changes.

Also lints the ConnectivityRepository(Test) files, since they apparently
were incorrectly linted before.

Bug: 238425913
Test: atest MobileInputLoggerTest
Test: `adb shell dumpsys activity service
com.android.systemui/.SystemUIService MobileInputLog` -> verify logs
appear
