220e34b69d LibWeb: Add Canvas Context2D basic text align and text baseline support
Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.

45f86466bb LibWeb: Add initial implementation of CRC2D.globalAlpha
Works for fills and strokes (using colors, gradients, or patterns),
along with images.

fill_rect() has been updated to use fill_path(), which allows it to
easily transform the rect, and already supports opacity.

4f2770a745 LibWeb: Apply canvas transform while building paths
The transform can change between path building operations (and before
the path is filled or stroked). This fixes the sun ray backgroun on
the https://www.kevs3d.co.uk/dev/html5logo/ canvas demo.

The new rasterizer can now handle floating point positions nicely so
this rounding can be removed.

It is faster to avoid the extra overhead/indirection of paint styles if
possible.

20e9213cc4 LibWeb: Add initial implementation of CRC2D.clip()
This allows clipping your drawing by any path you like! To do this
all painting has been wrapped around a new draw_clipped() helper
method, which handles the clipping before/after painting.

Note: This clipping is currently missing support for intersecting
clip paths.

e77552519e LibWeb: Implement CRC2D.imageSmoothingEnabled
We now select between nearest neighbor and bilinear filtering when
scaling images in CRC2D.drawImage().

This patch also adds CRC2D.imageSmoothingQuality but it's ignored for
now as we don't have a bunch of different quality levels to map it to.

Work towards #17993 (Ruffle Flash Player)

b75b7f0c0d LibJS+Everywhere: Propagate Cell::initialize errors from Heap::allocate

cells. Callers in infallible contexts get a FIXME.

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.

6e7459322d AK: Remove StringBuilder::build() in favor of to_deprecated_string()
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.

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.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

66a428ae03 LibJS+LibWeb: Return non-const types from Ptr class operators
Even if the pointer value is const, the value they point to is not
necessarily const, so these functions should not add the qualifier.

This also removes the redundant non-const implementations of these
operators.

e72896e35e LibWeb: Get default fonts via Platform::FontPlugin
Instead of asking Gfx::FontDatabase for the "default font" and the
"default fixed-width font", we now proxy those requests out via
the Platform::FontPlugin. This will allow Ladybird to use other default
fonts as fallback.

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.
