Update HasOverflowClip for body after style recalc.
The HasOverflowClip flag on LayoutBlock is updated as part of SetStyle,
but for body, the flag may need to change as a result of changing the
overflow property on the root element.
This CL always updates the flag for body after a style recalc. It's
only strictly necessary to do this if the root element is recalculated
and changes overflow between visible and a non-visible overflow, and at
the same time, the body element does not need a style recalc. Those
checks would complicate the code with little gain, so left to be done
unconditionally.
This fixes scrollingElement.html and HTMLBody-ScrollArea_quirksmode.html
in wpt/cssom-view. The latter had a bug that it didn't clear the
"scroll" values set to check if overflowY could be set, which caused a
subsequent test to incorrectly fail in both Blink and Gecko.
