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 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.
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.
The spec is unclear about when exactly we should parse the style sheet.
Previously we'd do so before calling this algorithm, which was
error-prone, as seen by the bug fixed by the previous commit. The spec
for step 1 of "create a CSS style sheet" says:
1. Create a new CSS style sheet object and set its properties as
specified.
The definitions linked are UA-defined enough that it seems reasonable to
put the parsing here. That simplifies the user code a little and makes
it harder to mess up. It does raise the question of what to do if
parsing fails. I've matched our previous behaviour by just logging and
returning in that case.
While I'm modifying this method, I've also converted the bool params to
enums so they're a little clearer to read.
Before this change, we assigned the style sheet's location *after* its
content rules were parsed and added to it. This meant any `@import`s
would try to fetch their style sheet before they knew the URL they
should fetch it relative to.
This change adds “default step” and “step scale factor” handling for all
remaining HTMLInputElement input types for which the spec defines such
and that we didn’t yet have handling for.
With this change we save a copy of of scroll state at the time of
recording a display list, instead of actual ScrollState pointer that
could be modifed by the main thread while display list is beings
rasterized on the rendering thread, which leads to a frame painted with
inconsistent scroll state.

This will be needed by Streams. To support this, we now store callbacks
in a hash table, keyed by an ID. Callers may use that ID to remove the
callback at a later point.
While debugging a spec-compliant implementation of ReadableStreamPipeTo,
I spent a lot of time inspecting promise internals. This is much less
noisy if we halve the number of temporary promises.
To prepare for introducing a CSS::URL type, we need to qualify any use
of LibURL as `::URL::foo` instead of `URL::foo` so the compiler doesn't
get confused.
Many of these uses will be replaced, but I don't want to mix this in
with what will likely already be a large change.
Instead of wrapping all non-movable members of TransportSocket in OwnPtr
to keep it movable, make TransportSocket itself non-movable and wrap it
in OwnPtr.
We were handling removing the style sheet from the shadow root, but not
appending to it. Fixing this also revealed a bug that a removed link
element would always try to remove from the document's list, as the
root is no longer the shadow root it's in. The fix is to use the passed
in old root to remove the style sheet from.

There's a bit of a UTF-8 assumption with this change. But nearly every
caller of these methods were immediately creating a String from the
resulting ByteString anyways.
With this change, the responsibility for prepending messages with their
size and ensuring the entire message is received before returning it to
the caller is moved to TransportSocket. This removes the need to
duplicate this logic in both LibIPC and MessagePort.
Another advantage of reducing message granularity at IPC::Transport
layer is that it will make it easier to support alternative transport
implementations (like Mach ports, which unlike Unix domain sockets are
not stream oriented).
The special empty value (that we use for array holes, Optional<Value>
when empty and a few other other placeholder/sentinel tasks) still
exists, but you now create one via JS::js_special_empty_value() and
check for it with Value::is_special_empty_value().
The main idea here is to make it very unlikely to accidentally create an
unexpected special empty value.
