On master, easylogging's Debug level was disabled unless OVRAS was built
with debugSymbolsAndLogs (ENABLE_DEBUG_LOGGING). The qt6 branch switched
to qDebug() and lost that: debugLoggingEnabled was left unused, and all
debug output reached the log. On the Steam Frame it filled with
"updateAllPulseData done." about every 11 ms, as the audio tab reads the
microphone's mute state on every tick.
setUpLogging() now disables debug output through a logging filter rule.
QT_LOGGING_RULES="*.debug=true" takes precedence and turns it on again
for troubleshooting without a rebuild.
