Made QGtkStyle internal

We will take this opportynity to remove various QStyle specializations
from the public API in Qt5. This gives us much more freedom, for
example some styles could be even separated out of QtWidgets and be
provided as plugins instead.

=> Use QStyleFactory and/or QProxyStyle instead of creating an instance
or inheriting QGtkStyle directly.
