4d64f21fa5 LibWeb: Give IDL exposed PlatformObjects an InterfaceName 
By making use of the WEB_PLATFORM_OBJECT macro we can remove
the boilerplate of needing to add this override for every
serializable platform object so that we can check whether they
are exposed or not.

e6dbcccb99 LibGfx+LibMedia: Send video frames to Skia as subsampled YUV 
This saves us from having our own color conversion code, which was
taking up a fair amount of time in VideoDataProvider. With this change,
we should be able to play high resolution videos without interruptions
on machines where the CPU can keep up with decoding.

In order to make this change, ImmutableBitmap is now able to be
constructed with YUV data instead of an RBG bitmap. It holds onto a
YUVData instance that stores the buffers of image data, since Skia
itself doesn't take ownership of them.

In order to support greater than 8 bits of color depth, we normalize
the 10- or 12-bit color values into a 16-bit range.

88c4814de6 LibGfx+LibWeb: Extract bitmap-to-buffer conversion into LibGfx 
This factors the conversion logic to be independent from WebGL code,

can't run in CI).

5b88b76b84 LibWeb: Deduplicate WebGL1 implementations from WebGL2 
This makes the WebGL2 implementation file inherit from the WebGL1
implementation file. This is actually closer to what the IDL files
describe and allows us to not have to maintain two copies of the same
functions.

7a1668fe22 LibWeb: Switch include in WebGLRenderingContextImpl to OpenGL ES 3 
The reasoning behind this is that in the next commit some of the WebGL2
specific parameters will be moved here. This header is needed to give
us access to those defines. Note that when in WebGL1 nothing from ES3
will be used as it's locked behind WebGL2 checks (it wouldn't work
anyways as we request ES2 from ANGLE).

c70886ab1f LibWeb: Split off WebGLRenderingContextImpl to Impl and Overloads 
This is more like what the IDL files specify with two different mixins,
but the inheritance structure here is slightly different for easier
maintenance. This will also allow the WebGL2 Impl to inherit from the
WebGL1 Impl as WebGL versions don't share the functions defined in the
Overloads interfaces.
