Support contain-intrinsic-size auto && <length>
https://bugs.webkit.org/show_bug.cgi?id=239450
Reviewed by Oriol Brufau.
This patch adds support to value auto && <length> for contain-intrinsic-size.
Per [1], with the auto && <length> value,
the last remembered size is the explicit intrinsic size if the box is skipping
its content.
The last remembered size is determined when ResizeObserver events are
delivered. m_resizeObserverForContainIntrinsicSize
in Document is created specifically to handle the last remembered size.
CallbackForContainIntrinsicSize in Document is
used to handle the lastRememberedSize. Because this ResizeObserver is for
inside use, so we create a interface
NativeResizeObserverCallback for native use. Now in ResizeObserver there are
two kinds of callbacks:
JSResizeObserverCallback and NativeResizeObserverCallback, only one could be
initialized.
The resizeObserver would observe the target if contain-intrinsic-size is valued
auto && <length>, otherwise unobserve
it and clear the lastRememberedSize. If an observed target is hidden or
skipping its content, unobserve it. Similarly,
if an observed target is removed from DOM tree, unobserve it and clear the
lastRememberedSize.
