This Intrinsics object hangs off of a new HostDefined struct that takes
the place of EnvironmentSettingsObject as the true [[HostDefined]] slot
on JS::Realm objects created by LibWeb.
This gets the intrinsics off of the GlobalObject, Window, similar to the
previous refactor of LibJS to move the intrinsics into the Realm's
[[Intrinics]] internal slot.
A side effect of this change is that we cannot fully initialize a Window
object until the [[HostDefined]] slot has been installed into the realm,
which happens with the creation of the WindowEnvironmentSettingsObject.
As such, any Window usage that has not been funned through a WindowESO
will not have any cached Web prototyped or constructors, and will not
have Window APIs available to javascript code. Currently this seems
limited to usage of Window in the CSS parser, but a subsequent commit
will clean those up to take Realm as well. However, this commit compiles
so let's cut it off here :^).
Until now, we've been using CSS::LengthPercentage, sometimes wrapped in
Optional, to represent CSS sizes.
This meant we could not support modern values like `min-content`,
`max-content`, `fit-content(<length>)`. We were also conflating `none`
and `auto` which made the `min-*` and `max-*` properties confusing.
The new CSS::Size class covers all possible size values as individual
substates. It'll be quite a bit of work to make all layout code aware of
the additional features, this patch merely makes the new type available.
Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
This remained undetected for a long time as HeaderCheck is disabled by
default. This commit makes the following file compile again:
// file: compile_me.cpp
#include <LibWeb/HTML/CrossOrigin/CrossOriginOpenerPolicy.h>
// That's it, this was enough to cause a compilation error.
Likewise for most other files touched by this commit.
This style value holds a list of CSS filter function calls e.g.
blur(10px) invert() grayscale()
It will be used to implement backdrop-filter, but the same style value
can be used for the image filter property.
(The name is a little awkward but it's referenced to as
filter-value-list in the spec too).

Instead of using Core::EventLoop and Core::Timer directly, LibWeb now
goes through a Web::Platform abstraction layer instead.
This will allow us to plug in Qt's event loop (and QTimer) over in
Ladybird, to avoid having to deal with multiple event loops.
