Inline reconstruct#12602
<!-- Please describe your changes on the following line: -->
This PR fixes two different issues:
1) In non-incremental layout mode if the inline node hasn't changes - the style pass was skipped, that leads to the corresponding ConstructionResult was not produced. When the parent was rebuilt, the child without the ConstructionResult was omited.
2) When the opacity was changed (or other style change, causing only repaint) for image (and others, producing only ConstructionItem) the damage is calculated only from children's flows, not from individual fragments. So for now, let's pretend we've newly constructed the ConstructionItem and thus need to rebuild the parent's flow.

Support multiple backgrounds in both servo and stylo
(Commits do not build individually, but split up for review)
These patches make all of the background- properties accept multiple values, and add the layout code to display them.
Still needs some cleanup, and some testing, but it seems to work.
