Improve "Checking to restart" protolog

This protolog is useful to know why an app gets restarted when a
configuration has changed, but it dumps info in hex format, so
pretty hard to read for humans.

Flag: EXEMPT log change only
Bug: 400335021
Test: adb shell cmd protolog_configuration logcat enable WM_DEBUG_CONFIGURATION
