Summary [GTK][WPE] Dynamic scrollbar-width changes are not repainted

On WPE and GTK, ScrollbarsControllerGeneric does not override scrollbarWidthChanged(), so dynamic CSS scrollbar-width changes are not repainted until the next full layout invalidation. Mac and Remote controllers already handle this. This blocks WPT css/css-scrollbars/scrollbar-width-paint-001..006.html.
