LibWeb: Invalidate viewport's text blocks cache on layout update

Browse source 
156c1083e9 introduced a text blocks cache
for better performance when searching through text on a page, but when
we partially recreate the layout tree, this cache does not get
invalidated. We now rebuild the entire text blocks cache after a layout
update.
