Add support for shared memory creation in WebAssembly memory API.
This API is needed for WPT tests that use shared array buffers.

This change implements spec-conformant computation of default ARIA roles
for elements whose expected default role depends on the element’s
context — specifically, either on the element’s ancestry, or on whether
the element has an accessible name, or both. This affects the “aside”,
“footer”, “header”, and “section” elements.
Otherwise, without this change, “aside”, “footer”, “header”, and
“section” elements may unexpectedly end up with the wrong default roles.
Details' contents matches a new details-content pseudo element.
Further work is required to make this pseudo-element behave per spec.
This pseudo should be element-backed per

Introduced in bd932858, the code would try to move `result.color_space`
into the ImmutableBitmap created for each single frame of an image. For
animated images, this would result in a use-after-move from the second
frame.
This corresponds to https://github.com/whatwg/html/pull/10753
WHile I was at it, I've also moved the checks inside the spin callback,
and reformatted the spec comments to match our style.
This patch introduces the `Gfx::ColorSpace` class, this is basically a
serializable wrapper for skia's SkColorSpace. Creation of the instances
of this class (and thus ICC profiles parsing) is performed in the
ImageDecoder process. Then the object is serialized and sent through
IPC, to finally be handed to skia for rendering.
However, to make sure that we're not making all LibGfx's users dependent
on Skia as well, we need to ensure the `Gfx::ColorSpace` object has no
dependency on objects from Skia. To that end, the only member of the
`ColorSpace` class is the opaque `ColorSpaceImpl` struct. Though, there
is on issue with that design, the code in `DisplayListPlayer.cpp` needs
access to the underlying `sk_sp<SkColorSpace>`. It is provided by a
template function, that is only specialized for this type.
Doing this work allows us to pass the following WPT tests:

- https://wpt.live/css/css-color/tagged-images-003.html
- https://wpt.live/css/css-color/tagged-images-004.html

Note that SkColorSpace support quite a limited amount of color spaces,
so color profiles like the ones in [1] or the v4 profiles in [2] are not
supported yet. In fact, SkColorSpace only accepts skcms_ICCProfile with
a linear conversion to XYZ D50.

This fixes the problem when surface is not allocated because context is
not initialized yet, even though canvas size is non-zero.
Fixes broken WebDriver screenshot endpoint.
For now only macOS is supported.
IOSurface is used as a backing store because it will allow us to read
it from Skia and write to it from OpenGL without any extra copying:
- ANGLE_metal_texture_client_buffer extension is used to create
EGLSurface from IOSurface.
- Then the same IOSurface is wrapped into Metal texture and passed to
Skia allowing to share the same memory between Skia Metal backend and
ANGLE.
Previously, constructing a PaintingSurface from an IOSurface required
wrapping IOSurface into a Metal texture before passing it to the
PaintingSurface constructor. This process was cumbersome, as the caller
needed access to a MetalContext to perform the wrapping.
With this change SkiaBackendContext maintains a reference to the
MetalContext which makes it possible to do:
IOSurface -> MetalTexture -> SkSurface within a PaintingSurface
constructor.
Implement transfer logic for ArrayBuffer and ResizableArrayBuffer.
Change TransferDataHolder data type to Vector<u32> to reuse existing
serialization infrastructure.
Fix 5 WPT tests in `window-postmessage.window.html` that relates to
transport.
Fix `LibWeb/Text/input/Worker/Worker-postMessage-transfer.html`.
The latter is currently ignored due to flakiness, no rebaseline is
needed.
During serialization with transfer, initialize memory with known index
and initialize Serializer at position that dependent on the memory.
This is mandatory to make ArrayBuffer transport to work. It also happens
to fix 4 WPT tests, that are related to curcular references during
serialization.
The 'reason' was getting initialized to 'empty' state when not
provided through the constructor, which results in a crash when
accessed through throw_dom_exception_if_needed in the generated
IDL getter.
All global objects current need to be event targets so that they
can have events dispatched to them. This allows for removing of
verify_cast for these global objects.
The rules for parsing integers don't specify an upper bound on the
value that can be returned, so the `parse_integer_digits` method can be
used to check whether the given arbitrarily-large StringView is valid
according to these rules. The `parse_integer` and
`parse_non_negative_integer` methods would fail for values larger than
2147483647 when they shouldn't have.
Setting the `width` or `height` properties of `HTMLCanvasElement` to a
value greater than 2147483647 will now cause the property to be set to
its default value.
