[CSS Grid Layout] Content sized tracks must clear the override height

[CSS Grid Layout] Content sized tracks must clear the override height

Content sized tracks depend on grid item's height to determine their
height. If the item was stretched and needs a new layout, we must clear
the override height to properly.

However, we can't just clear the override height because we need to know
it was set, hence we would need grid item's intrinsic height instead of
its logicalHeight in case it does not need such new layout.

The patch looks good but we need more tests. The description mentions content
sized tracks but the tests do not cover such cases. Also we need to add spanning
items to them.
