Perform Windows and Edge optimizations

• Check for service process before driver.quit() on Windows
  -- (This prevents a hanging process during cleanup if a driver was already quit. Sometimes people forget that SeleniumBase already quits drivers automatically at the end of tests, so if they manually try to quit a driver during a test, then during the cleanup phase there would be a hanging process on Windows when SeleniumBase tries to quit the driver again. Now, a check is performed to find out if drivers have already been quit.)
  -- (In the case of tests that spin up multiple drivers using self.get_new_driver(), in SeleniumBase 2.4.22, a new method was added: self.quit_extra_driver(), which quits extra drivers safely, and then removes those drivers from the list of drivers to be quit automatically at the end of tests.)
• Update default EdgeDriver version if can't detect latest
