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.
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.
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`.

Add OffscreenCanvas to TexImageSource and CanvasImageSource.
Implement all the necessary features to make it work in all cases where
these types are used.
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.
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.
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
