PySide2: Replace macro check_qt_class by the Qt configure system

Query the feature properties of the configure system to check whether
a class is present instead of running a compile test in QtGui and
QtNetwork.

Remove the macro invocation from QtWigets since the results
(QtWidgets_OPTIONAL_SRC, QtWidgets_DROPPED_ENTRIES) were not used.
