Reduce mlaunch default verbosity from 5 to 2 (#1561)

* Reduce mlaunch default verbosity from 5 to 2

The default verbosity of 5 causes mlaunch to pass five -v flags to
devicectl, producing massive debug output (full device property trees,
connection details, capabilities) that clutters console logs. Reducing
to 2 keeps useful diagnostic info while removing the noise.

* Reduce logging verbosity by filtering out system logs in TestOrchestrator and adding a separate process log in AppBundleInformationParser.

* Reduce logging verbosity in MlaunchProcessManager and IMlaunchProcessManager by setting default verbosity to 0
