  [FFC] Add skeleton implementation for layout integration dependent functions (flexContainerMainSize/hypotheticalCrossSizeForFlexItems/collapseNonVisibleFlexItems)
https://bugs.webkit.org/show_bug.cgi?id=258248

Reviewed by Antti Koivisto.

These functions trigger layout on flex items while running flex layout and they need integration support (calling back in to render tree).
However currently FFC only works with "fixed" geometry meaning that we don't really need to run layout on flex items' subtrees.

(WebCore::Layout::FlexLayout::flexContainerMainSize const):
(WebCore::Layout::FlexLayout::hypotheticalCrossSizeForFlexItems const):
(WebCore::Layout::FlexLayout::collapseNonVisibleFlexItems):
