cbb4be3e5e LibWeb/CSS: Replace style-rule iteration methods with a generic one
I didn't want to add another set of boilerplatey tree-walking methods,
so here's a general-purpose one. :^)

`for_each_effective_rule()` walks the tree of effective style rules, and
runs the callback on each one, in either pre- or postorder.  The
previous `for_each_effective_style/keyframes_rule()` methods of
`CSSStyleSheet` are then reimplemented in terms of
`for_each_effective_rule()`, and we can get rid of their equivalents
elsewhere.

c0d7f748ed LibWeb: Avoid FlyString lookups when setting IDL interface prototypes
This commit introduces a WEB_SET_PROTOTYPE_FOR_INTERFACE macro that
caches the interface name in a local static FlyString. This means that
we only pay for FlyString-from-literal lookup once per browser lifetime
instead of every time the interface is instantiated.

e90752cc21 LibWeb: Add preliminary support for CSS animations
This partially implements CSS-Animations-1 (though there are references
to CSS-Animations-2).
Current limitations:
- Multi-selector keyframes are not supported.
- Most animation properties are ignored.
- Timing functions are not applied.
- Non-absolute values are not interpolated unless the target is also of
  the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px).
- The JavaScript interface is left as an exercise for the next poor soul
  looking at this code.

With those said, this commit implements:
- Interpolation for most common types
- Proper keyframe resolution (including the synthetic from-keyframe
  containing the initial state)
- Properly driven animations, and proper style invalidation

2692db8699 LibJS+Everywhere: Allow Cell::initialize overrides to throw OOM errors
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.

834202aeb9 LibWeb: Move setting of Web object prototypes to initialize()
This needs to happen before prototype/constructor intitialization can be
made lazy. Otherwise, GC could run during the C++ constructor and try to
collect the object currently being created.

a2ccb00e1d LibWeb: Remove unecessary dependence on Window from CSS classes
These classes only needed Window to get at its realm. Pass a realm
directly to construct CSS classes.

ffad902c07 LibWeb: Use cached_web_prototype() as much as possible
Unlike ensure_web_prototype<T>(), the cached version doesn't require the
prototype type to be fully formed, so we can use it without including
the FooPrototype.h header. It's also a bit less verbose. :^)

6f433c8656 LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.

There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.

c37820b898 Libraries: Use default constructors/destructors in LibWeb
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules

"The compiler is more likely to get the default semantics right and
you cannot implement these functions better than the compiler."

6fc1810190 LibWeb: Remove for_first_not_loaded_import_rule() :^)
This was only used for making sure `@import` rules got loaded, and since
they handle that themselves now, we can get rid of all this code!

439d978ea5 LibWeb: Make style-rule iteration aware of CSSMediaRule
The logic is handled by `CSSGroupingRule` and `CSSConditionRule`, so
`CSSMediaRule` only has to report if its condition matches.

Right now, that condition is always false because we do not evaluate the
media query.

0b23a20ad5 LibWeb: Add CSSConditionRule
https://www.w3.org/TR/css-conditional-3/#the-cssconditionrule-interface

This simply exposes a condition string, which is implemented differently
in each sub-class.
