Summary:
This change extracts functionalities from processwindows into a
introduced processdebugger that can be reused in native process
debugging.
The main reason is that the native process debugging
can't directly be based on processwindows or be implemented
as a pass-through to this plugin since the plugin has ties to
Target and Process classes that are needed in host debugging but
not necessary in native debugging.
