Remove StyleImage::SetIsLazyloadPossiblyDeferred

The only time when this is used is to set the value to true on a
StylePendingImage. The StylePendingImage is never read from or used
except for getting the underlying CSSValue though, making the store dead
and the method unused.
Also remove the cast from StyleImage to StyleFetchedImage, which is
unnecessary because the flag lives in the base class (StyleImage) and
is only set by the subclass constructors.
