[LayoutNG] Caching and OOF fragmentation

Don't return the cached layout result when block fragmenting
and the current fragment has an OOF child to ensure that such OOF
descendants get properly laid out. (Credit to mstensho@
for uncovering the fix).

Note: I also updated the check for HasOutOfFlowPositionedDescendants()
with NeedsOOFPositionedInfoPropagation() since that seems like a
more accurate check (although this change doesn't have any effect on
this test case).
