Remove dead code for EFillSizeType::kSizeNone

This enumeration value is only used during style resolution, and thus
there should be no need to handle it elsewhere.

This allows cleaning up the ShouldFullyInvalidateFillLayersOn*Change
helpers as well, removing the only users of

StyleImage: :UsesImageContainerSize() and in turn also
Image: :UsesContainerSize(), so removing those as well.
