Avoid appcompat logs if old or disabled 

For performance savings, we will only log appcompat changes to debug if
it targets the latest sdk version and it is not disabled. These can
still be turned back on with `adb setprop
log.tag.CompatChangeReporter=DEBUG`.

Test: atest PlatformCompatFrameworkTests; atest FrameworksServicesTests:ActivityManagerServiceTest; atest FrameworksServicesTests:ProcessRecordTests; atest FrameworksServicesTests:CompatConfigTest; atest FrameworksServicesTests:PlatformCompatTest
Bug: 323949942
