[css-flexbox] Correctly size flex rows with scrollbars

Flex items with overflow: scroll were not handled correctly when they *don't*
need to be stretched. We would double-count the scrollbar height.

This also merges constrainedChildIntrinsicContentLogicalHeight into its only
caller, which I think makes the code a bit clearer.

Found thanks to a new W3C test. It also fixes a TODO.
