[Hexagon] Add feature to copy logcat to --hexagon-debug and add new --sysmon-profile option to run sysmon profiler during the test

[nverke]

I added some things to the hexagon pytest plugin to make working on hexagon a little bit easier sometimes.

--hexagon-debug will now copy all of the logcat logs for the time period of the test and copy them back to your device.
--sysmon-profile will start the Sysmon Profiler before your run, shut it down afterwards and then copy the data back and parse it to html for you.

I would also run logcat -c before execution if --hexagon-debug is specified to clear out old logcat entries from previous runs.

I usually dont want to have this delete old logs because I sometimes find them useful. The logcat scanner should be able to accurately pickup the right logs for just the run. Ill add it as a separate option that can be used if desired.

Added the clear-logcat option and moved to the launcher as @mehrdadh requested.
