pointers and hacks.

f373ab7011 LibWeb: Bind WebGL uniform locations to their respective program 
The spec mandates that each uniform location object only gets used with
the program it was created with.

7d6212ae71 LibWeb: Ensure WebGL buffers don't mix between index and other data 
The spec mandates that a buffer during its lifetime can only get bound
to either an index buffer or any other type.

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.

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.

25d78f7c8e LibWeb: Implement WebGL2's readPixels with a byte offset argument 
We pass it in as a `void*` since that's what this API expects when you
have bound the GL_PIXEL_PACK_BUFFER buffer.

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.

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`.

e85b809f8d LibWeb+Meta: Move WebGL rendering context implementations in tree 
This copies the latest generated code in tree and then removes code
generation for the WebGL rendering contexts. This is because it didn't
add much value, and we can maintain the generated output instead of
both that and the generator itself.
