  [LFC][IFC] Introduce BlockLayoutState
https://bugs.webkit.org/show_bug.cgi?id=247780

Reviewed by Antti Koivisto.

In many cases child IFCs need to know about parent block level layout state. E.g how many lines the block still needs across sibling IFCs
when line-clamp is present, or where the intrusive, BFC level floats are.
