Currently if device set Android log level to Debug Chrobalt honors it. Disabling it enables us to build without Java debug logs in release builds.

Actually, can we change it to use the CoAT implementation?

This implementation can dynamically print logs with different levels, see instruction on https://g3doc.corp.google.com/company/teams/cobalt/team/first-party-ports/android/tips.md#add-logs-for-kimono

That's exactly what Log.java does. The PR here is only to strip logging in release build.
