Logging: use qCDebug/Warning/Info when for categorized logging

Browse Source 
When building qt with QT_NO_DEBUG/WARNING/INFO_OUTPUT set, then the
qDebug/Warning/Info macros expand to `QMessageLogger::noDebug`. That
helper is not defined to take a logging category or category function,
so using `qDebug(lcX, ...)` breaks the build. The correct way to emit
categorized logging is to use the qCDebug/Warning/Info macros.
