[NUI] Fix FlexLayout not to fill its parent with WrapContent

Previously, FlexLayout filled its parent even if it had WrapContent
Width/HeightSpecification.
Because FlexLayout's width and height always referred its parent's size.
(If Width/HeightSpecification is WrapContent, then Mode becomes AtMost.)

Now, FlexLayout does not fill its parent if it has WrapContent
Width/HeightSpecification.
