Reland "tint::transform::VertexPulling: require SingleEntryPoint" 

This is a reland of commit 63463c2f77

Original change's description:
> tint::transform::VertexPulling: require SingleEntryPoint
>
> This change the vertex pulling transform to look for the single vertex
> entry point in the module, instead of taking the entry point name in the
> config. This is necessary because the renamer needs to run before
> VertexPulling so that builtins like min() don't end up referring to the
> input WGSL. Putting the renamer before VertexPulling makes the config
> entry point name no longer match.
