[LayoutNG] Reuse line boxes when it is easy to resolve BFC offset

This patch allows reusing line boxes when it is easy to
resolve BFC offset. It was one of the most common criteria
that prevents reusing.

HandleInFlow resolves BFC for non-empty inline formatting
context. The reusability increases by moving the logic to
after that.

This patch improves line-layout-repeat-append by ~60%.
