Remove gtk2 style from qtbase, it will be moved to qtstyleplugins

This will allow us to drop gtk2 support from qtbase in future,
while still providing the gtk2 style for those who want to use it.

Also with moving to qtstyleplugins, the code can be simplified
because we can directly link to libraries we need, instead of using
QLibrary.

[ChangeLog][QtWidgets] Remove QGtkStyle, it is now provided in
qtstyleplugins repository.
