2fa84f1683 LibWeb: Properly propagate errors for Node set_text_content 
This function was supposed to throw errors even before the TrustedTypes
spec thanks to the CharacterData replaceData call but had a MUST.

This changes this to ensure this function can throw an error

3593c3b687 LibWeb: Throw out decoded UTF-32 data in HTMLTokenizer after parser runs 
This ends up saving quite a bit of memory on many pages, since UTF-32
uses 4 bytes per code points.

As an example, it reduces the footprint on https://gymgrossisten.com/
by 2 MiB.

b10f2993b3 LibWeb: Use Optional<ssize_t> for the HTMLTokenizer insertion points 
Instead of making a custom struct, we can just use Optional here,
to make the code feel a bit more idiomatic.

62ae4e878f LibWeb: Implement support for drawing with CanvasPattern 
We already had the API, but drawing to the canvas was not affected by
any created CanvasPattern. This moves CanvasPatternPaintStyle to LibGfx
so we don't have to reach into LibWeb, and implements the plumbing to
let Skia use images as a fill pattern.

0b715b20a2 LibWeb: Make HTML fragment parsing return ExceptionOr 
Update Element::parse_fragment and Node::unsafely_set_html to
propagate exceptions.

This refactor is needed as a prerequisite for implementing the XML
fragment parser, which requires consistent error handling in fragment
parsing.

2fd424ccb6 LibWeb: Draw canvas arcs and ellipses correctly when radius is zero 
In this case, we should just draw a line from the last point in the
path to the start point. Previously, a division by zero caused nothing
to be drawn.

f49cf75d44 LibWeb: Don't pass unnecessary PropertyComputationDependencies struct 
Since we now have access to the `AbstractElement` through the
`ComputationContext` we can just set the flag that this element relies
on tree counting functions directly, no need to pass this struct around.

5b9a36b172 LibWeb: Pass AbstractElement in ComputationContext 
Passing the `AbstractElement` rather than the
`TreeCountingFunctionResolutionContext` allows us to only compute the
resolution context when necessary (i.e. when we actually need to resolve
a tree counting function)

`dirtyWidth` and `dirtyHeight` arguments.

2404f95e03 LibWeb: Invalidate style for tree counting functions when required 
We mark any element that relies on tree counting functions as needing a
style update when a sibling is inserted/removed.

9cd23e3ae5 LibWeb: Compute and propagate tree-counting function resolution context 
Tree counting functions should be resolved at style computation time -
to do this we will need to know the element's sibling count and index.

This commit computes that information and propagates it to the various
`StyleValue::to_computed_value` methods.

d4df0e1db9 LibWeb: Make Event.currentTarget return WindowProxy instead of Window 
Make WindowProxy implement the EventTarget interface. Add a new method
current_target_for_bindings() that returns a WindowProxy object instead
of directly exposing the Window object.

These changes fixes several WPT tests that contain `window ===
currentTarget`.

9e838cffb4 LibWeb: Copy "is inert" attribute into Paintable 
...instead of reaching into DOM tree during hit-testing in order to
figure out if an element is inert. This is a part of the effert to make
possible running hit-testing solely based on data contained by the
paintable tree.
