ccea69ad40 LibWeb: Add special handling for text-align when applied to tables 
This matches what other engines do, and stops table content from being
misaligned.

cc9de38ea4 LibWeb: Fix null pointer dereference in DOM::Node::remove() 
Instead of blindly dereferencing m_registered_observer_list, just use
the add_registered_observer() helper.

Fixes #22005

bdac94870c LibWeb: Convert Element "attribute change steps" from vector to virtual 
By using a virtual function and overriding it on HTMLSlotElement, we
shrink every DOM element by 24 bytes. :^)

48dbec8a9e LibWeb: Allocate storage for pseudo element layout nodes on demand 
This saves us 64 bytes for every element that doesn't have pseudo
elements associated with it. Which is most of them. :^)

37505d9746 LibWeb: Allocate storage for pseudo element custom properties on demand 
Most elements don't have pseudo elements with CSS custom properties.
By only allocating this data structure when it's used, we can shrink
most elements by 208 bytes each. :^)

9edfd5e360 LibWeb: Only allocate DOM::Node registered observer list on demand 
Most DOM nodes don't have registered mutation observers, so let's put
the metadata about them behind an OwnPtr to save space in the common
case.

Saves 16 bytes per DOM node that doesn't have registered observers.

c1fd55ce94 LibWeb: Only allocate EventTarget listener/handler storage on demand 
This shaves 40 bytes off of all EventTargets that don't actually get
listeners or handlers attached (which is most of them).

a71eaefdf6 LibWeb: Make EventTarget::activation_behavior a virtual function 
(Instead of using an AK::Function on EventTarget). This shaves 48 bytes
off of every EventTarget instance.

bfd354492e LibWeb: Put most LibWeb GC objects in type-specific heap blocks 
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.

This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.

I left a few types unconverted to this mechanism because I got tired of
doing this. :^)

eca9874e56 LibWeb: Port Element::attribute_changed from DeprecatedString to String 
Which as you would expect has a bunch of fallout, but also results in a
whole lot of awkward conversions falling away.

6a2a7cad61 LibWeb/LibJS: Avoid GC visit of raw pointers where possible 
This is mostly motivated for aesthetics, but also helps avoid some null
checks when we have a NonnullGCPtr<T> or in some cases a T&.

ef71f46da6 LibWeb: Flesh out "scroll a target into view" spec implementation 
This change fixes regressed Acid2 test and now we at least can see
the face after clicking "Take The Acid2 Test" link.

The same limitations regarding construction of Window apply to all
WorkerGlobalScope classes as well.

3ff481938e IDL: Fix syntax errors 
All attributes must have an "attribute" keyword, and "any?" is invalid

45b63b463a LibWeb: Add Element::for_each_attribute(Function<void(Attr const&)>) 
This is useful when you are wanting to interate over attributes and need
more information than just the name and value.

13ae2a4dab LibWeb: Store all timelines associated with a document on the document 
This will be required for propagating the current animation time to all
relevant timelines, which each propagate that time to all of their
relevant animations.

22f6abe5d6 LibWeb: Remove DeprecatedString impls of get_elements_by_tag_name{_ns} 
No IDL file pulls in these requiring DeprecatedString support, so we
are now able to remove these functions! :^)

Also leave a FIXME while we are at it, as ideally this function would
take an Optional<FlyString> - but the IDL generator does not currently
support this.

1812221a2d LibWeb: Add FlyString versions of NamedNodeMap::get_attribute_ns 
This is the API for NamedNodeMap which we are wanting to eventually use
instead of taking a StringView. Currently we just end up deferring to
the StringView versions of these functions, but at some stage in the
future, this will allow us to have O(1) comparison when making attribute
lookups.

In the meantime, the advantage of this API is that it makes it much less
awkward to use than the StringView variant when you have an
Optional<FlyString> namespace to pass through.

Andreas Kling
3ff81dcb65 LibWeb: Make Web::Namespace::Foo strings be FlyString 
This required dealing with a *lot* of fallout, but it's all basically
just switching from DeprecatedFlyString to either FlyString or
Optional<FlyString> in a hundred places to accommodate the change.

cdbde1765a LibWeb: Skip assigning slottables for non-shadow roots 
For example, on https://html.spec.whatwg.org, there are hundreds of
thousands of nodes. This method is invoked as each node is inserted.
Traversing the entire tree each time takes a prohibitively long time,
so let's bail early when we know the operation is a no-op.

Timothy Flynn
f3e14d7f64 LibWeb: Use correct variable when handling slottables in node insertion 
Errantly copied the variable name from the spec. The `node` variable in
this scope is what we passed to Node::insert_before; `node_to_insert` is
what the spec is actually referring to as `node` here.

f9cab320e6 LibWeb: Only propagate CSS overflow to the viewport once per tree build 
Before this change, we were doing it after every layout, which meant
that already-propagated overflow could be propagated again, which led to
incorrect scrolling behavior.

f5771a5789 LibWeb: Check node type first in fast_is<ShadowRoot>() 
We know that shadow roots are always document fragments, so we can
check that before calling is_shadow_root() to avoid the cost of
a virtual call.
