Fix Android WebView hittest

WebView::hitTestResultAt takes window coordinates that are
not scaled by pageScaleFactor (same as gesture input event
coordinates). So scale WebView::hitTestResultAt coordinates
by pageScaleFactor.

Remove USE(GTK) reference from Tools/DumpRenderTree/

USE(GTK) was used to reference defined(TOOLKIT_GTK) from Chromium land.
However it was confusing and the only reason Tools/DumpRenderTree
needed its own config.h.
    
This change removes USE(GTK) and config.h, replaced by Chromium style
defined(TOOLKIT_GTK).
