These are slightly unfortunate as we're crossing the library boundary,
but there's precedent with Object::is_dom_node(), and these are just
knocking down a few more items that were showing up in profiles.
The remaining AOs can stay where they are. This patch just sorts them in
spec order to match the other AO files. Section 8.1 is last, however, as
these are all templates and need the declarations of other AOs above.
The main streams AO file has gotten very large, and is a bit difficult
to navigate. In an effort to improve DX, this migrates TransformStream
AOs to their own file.

The spec algorithms now use "the relevant global object's associated
document", so remove the concept of the History object itself having an
associated document. The spec has also combined the implementations for
forward/back/go so I've matched that too.

I've also split the `Document::has_focus()` method for clarity. Actually
implementing the "has focus steps" turns out to be quite involved so
I've left it for now.
This fixes Layout/input/dialog-open-modal.html which began flaking
super hard after the preceding commits that reduced style invalidation
for focus-related pseudo class selectors.
We achieve this by keeping track of all checked pseudo class selectors
in the SelectorEngine code. We also give StyleComputer per-pseudo-class
rule caches.
Previously, `CSSStyleSheet.replace()` and `CSSStyleSheet.replaceSync()`
parsed the given CSS text into a temporary stylesheet object, from
which a list of rules was extracted. Doing this had the unintended
side-effect that a fetch request would be started if the given CSS text
referenced any external resources. This fetch request would cause a
crash, since the temporary stylesheet object didn't set the constructed
flag, or constructor document. We now parse the given CSS text as a
list of rules without constructing a temporary stylesheet.
This was actually an older change to the Streams spec that we missed
when we implemented TransformStreams. This fixes a crash in the imported
WPT tests.

These callbacks are evaluated synchronously via JS::Call. We do not need
to construct an expensive RootVector container just to immediately
invoke the callbacks.
Stylistically, this also helps indicate where the actual arguments start
at the call sites, by wrapping the arguments in braces.
