[GTK][WPE] Limit the damage region of the scrollbar to the region actually
painted
https://bugs.webkit.org/show_bug.cgi?id=316268
Reviewed by Carlos Garcia Campos.
The whole scrollbar layer was always damaged while the overlay scrollbar is
hiding even though the most part of the overlay scrollbar is transparent. Only
the visible part, scrollbar thumb area, should be damaged during the hiding
animaiton.
