When that extensions is enabled we should allow getting the parameter
value of MAX_COLOR_ATTACHMENTS_WEBGL.

044ac2dd28 LibWeb: Fix WebGL getError
getError was just calling out to glGetError and never checking our
error value that we were maintaining ourselves.

e7aeb71d29 LibWeb: Move WebGL error variable to WebGLRenderingContextBase
Implementations in both WebGL1 and WebGL2 were the same and most
probably will stay the same.

6c115171da LibWeb: Split off WebGL2RenderingContextImpl to Impl and Overloads
This mostly analogous to the previous commit that does the same with
the WebGL1 Impl file.

8adde0980a LibWeb/WebGL: Respect UNPACK_PREMULTIPLY_ALPHA
Fixes splats on https://superspl.at having dark splotches, as they
expect textures with unpremultiplied alpha.

bc3761b40d LibWeb: Stubout WebGL2 getParameter(MAX_CLIENT_WAIT_TIMEOUT_WEBGL)
The spec actually mandates that clientWaitSync actually has a time
limit and this is a way to get it. For now just return infinity as this
is required of SpectorJS to work.

3e7061da40 LibWeb/WebGL: Respect UNPACK_FLIP_Y_WEBGL pixel storage parameter
When this is true, we have to vertically flip TexImageSource provided
images before uploading them.

Fixes several graphical glitches on Google Maps.
Fixes globe being upside down on Shopify's homepage.
Likely fixes more websites.

ab3eb9adab LibWeb/WebGL: Replace manual pointer math with Span
This deduplicates a lot of sensitive pointer math by using Span, which
performs this math for us with more safety checks and with type
information.

This also allows us to use the correctly typed Span for typed arrays,
which automatically fixes srcOffset to now offset by the number of
elements instead of bytes. This goes for srcLengthOverride too.

Fixes the Rive animations on Shopify's homepage not appearing.
Fixes some Unity applications such as ArcViewer having missing
graphics.

up duplicated between WebGL 1 and 2 contexts.

d54cab60a8 LibWeb/WebGL: Define Float32List exactly like in the spec
Use `Float32Array or sequence<GLfloat>` instead of
`BufferSource or sequence<GLfloat>`. This meaningfully changes behavior
for `Float16Array` and `Float64Array`: they are now converted to
`sequence<GLfloat>` by iterating the typed array, rather than being
treated as a `BufferSource`. As a result, many WebGL calls now work
correctly where we previously crashed in `VERIFY_NOT_REACHED()` due to
the assumption that a `BufferSource` was always a `Float32Array`.

8e453d5069 LibWeb/WebGL: Preserve original bound objects to return in getParameter
Required by https://qwasm2.m-h.org.uk, which adds a custom `name`
attribute to objects it generates. It then gets some of these objects
out with getParameter, and expects the `name` attribute to be there.

cf730870c5 LibWeb: Save WebGL context pointer in WebGLObject
This way we could be sure that context object won't be deallocated
before any of the objects that belong to it.

Having a context pointer is also going to be used in upcoming changes
to generate an INVALID_OPERATION error if an object does not belong to
the context it's being used in.

f87041bf3a LibGC+Everywhere: Factor out a LibGC from LibJS
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:

 * JS::NonnullGCPtr -> GC::Ref
 * JS::GCPtr -> GC::Ptr
 * JS::HeapFunction -> GC::Function
 * JS::CellImpl -> GC::Cell
 * JS::Handle -> GC::Root
