Remove deprecated Q_WS_* defines that are removed in Qt5
Rename ControlPushButtonTest to WPushButtonTest.
Define the prober QT_XXX_LIB CPPDEFINES for the OS X build. These are copied verbatim from qt4.py and qt5.py. We should get qt4/5.py fixed for OS X building and remove our special-casing of OS X.
