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).

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.

LibWeb/WebGL: Use surfaceless contexts when making a context current
...
After we bind the surface to the context for the first time when
allocating the backing image, it internally has a permanent reference
count above 0.
If we switch to a different context and back, the switch back will fail
because the surface has a reference count, which makes ANGLE think
we're trying to use it on a different thread.
However, we can avoid this by using surfaceless contexts, since we
don't use the default framebuffer.
Fixes multiple WebGL contexts on the page freezing.
