This function should return the automatic height of the formatting
context's root box.
Until now, we've been relying on some magical handshakes between parent
and child context, when negotiating the height of child context root
boxes. This is a step towards something more reasonable.
PageHost assumes page_did_layout() to be called when the layout
of the active document changes, however, it seems that sometimes
the layout can change on another document before the layout of
the active document has been calculated. This leads to a VERIFY()
being hit.
This commit now makes it so page_did_layout() is only called when
the document is the active document.

Tasks can run at any time in the future and GC can run in the time
between postMessage and running the task, meaning the message can be
reaped if we don't keep a handle to it.

We were forgetting to convert to and from BFC root relative coordinates
when calculating how much clearance was needed to get past floats.
This fixes the last remaining issue on Acid1, which is now perfect. :^)
Previously, we were using the full containing block width as a reference
for text-align values "right" and "center". This didn't take intruding
floats into account.
Layout box offset coordinates are always relative to their containing
block. Therefore, the functions that convert between coordinate spaces
should only visit containing blocks and apply their offsets, not *every*
box in the parent chain.
This fixes an issue where some floating boxes were unexpectedly far away
from their containing block.
This code generator no longer creates JS wrappers for platform objects
in the old sense, instead they're JS objects internally themselves.
Most of what we generate now are prototypes - which can be seen as
bindings for the internal C++ methods implementing getters, setters, and
methods - as well as object constructors, i.e. bindings for the internal
create_with_global_object() method.
Also tweak the naming of various CMake glue code existing around this.
These are exactly what's wanted by headless-browser too, so this saves
us some duplication. LibWeb already links LibCore so it should not
cause any issues for Ladybird.
This is used by window.close() programmatically, but of course the user
can also decide to close a top-level browsing context at any time by
closing the tab.
We now implement the browsing context's "set active document" algorithm
from the spec, as well as the "discard" algorithm for browsing contexts
and documents.
One edge case is left as a TODO() for now, since I'm not entirely sure
how to construct an element to those specifications.
With this patch, we can now run the Speedometer benchmark! :^)
