Remove relayout due to scrollbars taking up width

Remove relayout due to scrollbars taking up width

We only have overlay scrollbars, so we never need to
relayout due to the lack or presence of scrollbars.

Also remove a few stracking has*Scrollbar methods.

sky/engine/core/rendering/RenderLayerScrollableArea.cpp:418:
setHasHorizontalScrollbar(hasHorizontalOverflow);
These already have the hasHorizontalScrollbar() != hasHorizontalOverflow check,
so we don't need the autoHorizontalScrollBarChanged check anymore.
