bpo-36670: Multiple regrtest bugfixes (GH-16511)
 

* Windows: Fix counter name in WindowsLoadTracker. Counter names are
  localized: use the registry to get the counter name. Original
  change written by Lorenz Mende.
* Regrtest.main() now ensures that the Windows load tracker is also
  killed if an exception is raised
* TestWorkerProcess now ensures that worker processes are no longer
  running before exiting: kill also worker processes when an
  exception is raised.
* Enhance regrtest messages and warnings: include test name,
  duration, add a worker identifier, etc.
* Rename MultiprocessRunner to TestWorkerProcess
* Use print_warning() to display warnings.
