Need to include non-auto margins when resolving auto margins. (#46517)

Make sure that an auto margin doesn't receive the space actually taken
up by the non-auto margin on the other side of the box. Didn't get this
right for @page auto margins.

[layout] Fix block-in-inline within button to stretch by default.

Previously an InlineNode within a button would have its auto behaviour
set to shrink-to-fit. This was ok previously, but now use block layout
for buttons this triggered a behaviour change.

Ensure that all InlineNodes have their auto behaviour set to stretch
by default (and then implicitly all block-in-inlines).

Fix snap fling regression

In the linked bug, flings within large snap areas (constrained native
flings) would incorrectly snap based on the last finger position,
rather than the position the fling lands at.

This patch fixes this by ensuring that we always recompute the snap
strategy for a constrained native fling since we cannot know ahead of
time where that fling will land.

Referenced SVG elements in an external resource document match :target

Track which elements are referenced (by ) in an external resource
document by funneling the lookup through a special function on
SVGResourceDocumentContent that creates SVGResourceTarget objects for
each (valid) reference and lets the targeted element weakly reference
the object. While matching :target, the selector checker will check if
the element has a reference to an SVGResourceTarget object and let
:target match if it does.

Fix crash with unhandled promise rejections in worker Shadow Realms

Worker thread JS contexts have a promise rejection handler, but expect
the execution context to be a worker or worklet. Shadow realms are
initialized from these contexts. A method is added to
ShadowRealmGlobalScope to access this initiator context so the existing
logic can be reused.
