When `<body>` needs to calculate its size based on `<html>`'s size, that should be the size of the browser window itself.

Fixed layout flow tree JSON serialization
<!-- Please describe your changes on the following line: -->
The second argument for the `emit_struct()` is the number of fields, if given `0`, the output JSON will always be empty.
This is used in `./mach run -d -Z trace-layout https://servo.org`, which will dump the layout flow tree into a `layout_trace.json` file for debugging.
This also unblocks https://github.com/servo/servo/issues/12675

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.

Fix wrong calculation of inline element's block size
Border, padding and margin properties' top and bottom values of inline elements were affecting the element's height. It shouldn't affect it normally. Fixed it and added a test.

The style candidate cache had regressed a few times (see #12534), and my
intuition is that being able to disable all style sharing with a single rule in
the page is really unfortunate.
This commit redesigns the style sharing cache in order to be a optimistic cache,
but then reject candidates if they match different sibling-affecting selectors
in the page, for example.
So far the numbers have improved, but not so much as I'd wanted (~10%/20% of
non-incremental restyling time in general). The current implementation is really
dumb though (we recompute and re-match a lot of stuff), so we should be able to
optimise it quite a bit.
I have different ideas for improving it (that may or may not work), apart of the
low-hanging fruit like don't re-matching candidates all the time but I have to
measure the real impact.
Also, I need to verify it against try.
Fix absolute-flow's auto positioning
<!-- Please describe your changes on the following line: -->
If an absolute positioned flow has no top, bottom, left, right property, its hypothetical box position should be the margin-end of its previous sibling, not the border-end.

We got this wrong (I think it wasn't my fault actually), I was just writing a test for #12777 when I found this.
