QStyle: Set State_Enabled by default when painting style widgets. https://bugs.webkit.org/show_bug.cgi?id=112688

All Qt style widgets were painted with a disabled state, even when
they actually were enabled.
This change fixes it by setting State_Enabled as a default state,
which is then correctly removed when element is disabled.
