layout: Implement proper absolute child position for flexbox (#33346)

Browse source 
This implements the requirements outlined in the [flexbox specification]
about how to position absolute children of flex containers. We must
establish a static position rectangle (to use if all insets are auto)
and also align the child into that rectangle.

[flebox specification]: https://drafts.csswg.org/css-flexbox/#abspos-items
