Add windows platform plugin and its requirements

- executed pro2cmake script on windows qpa plugin
- added windowsuiautomation platformsupport project
- fixed plugin dlls and lib files to be written to the same path
- fixed an issue comErrorString which used implicit casting
  from QString to char*, but plugins are currently built
  with QT_NO_CAST_TO_ASCII
