InputDispatcher: use INFO for conditional logs

These logs currently don't show up in logcat due to b/282236272. Since
they're only enabled when the appropriate system property is set anyway,
it's not important that we keep them at the DEBUG level to avoid
spamming the logs, so upgrade them to INFO.

This CL was produced with the (Idea)Vim command:

    :%s/LOG_IF(DEBUG,/LOG_IF(INFO,/g

...followed by running Clang format.

Bug: 282236272
Test: $ atest --host inputflinger_tests
Flag: EXEMPT log only update
