Valentin Shergin 7bd0855650 Native implementation of <Image> intrinsic content size on iOS
Summary:
Now intrinsic content size of <Image> is implemented natively on iOS and now it is actually
`intrinsicContentSize`, not just overrided `height` and `width` styles (which was incorrect and hacky).
This change also removes support of nested content inside <Image>.
This is a first commit in the row where we improve <Image> implementation.
