        [WebGPU] Make WebGPU.framework's classes reference counted
        https://bugs.webkit.org/show_bug.cgi?id=233547

        Reviewed by Dean Jackson.

        This is a fairly mechanical change of replacing constructors with calls to create(), and
        changing instances to Ref<...>, and using -> instead of .

        There's one somewhat interesting design choice here. The header has things like:

        typedef struct WGPUAdapterImpl* WGPUAdapter;

        But we're using C++ so we want to have something like

        namespace WebGPU {
        class Adapter : public RefCounted<Adapter> {
            ...
        };
        }

        So we need to have some way of connecting these two things. This patch opts to do this like so:

        struct WGPUAdapterImpl {
            Ref<Adapter> adapter;
        };

        This isn't perfect, because it means that all method calls require a double dereference: one to
        dereference the WGPUAdapter to get the WGPUAdapterImpl, and one to dereference the Ref<Adapter>
        to get the Adapter. This is the most elegant solution for now, because it doesn't require any
        reinterpret_cast<>()'ing. This patch chooses this elegant solution, because premature optimization
        is the root of all evil.

        [WebGPU] Stub out methods in WebGPU.framework
        https://bugs.webkit.org/show_bug.cgi?id=232872

        Reviewed by Dean Jackson.

        This creates empty implementations for all the methods in WebGPU.framework.
        This means that there are now implementations for every API call, so PAL
        can successfully call into WebGPU.framework and link with it.

        Reviewed by Dean Jackson and Robin Morisset.

        We've gotten some requests to be able to use WebGPU from native code,
        without requiring all of WebKit. This patch creates a new Xcode project
        that creates a new framework for WebGPU, so these internal users can
        build it / include it in their own projects.

        This project has two targets: One for WGSL and one for WebGPU. WGSL
        creates a static library, and WebGPU links with it, and produces a
        framework. This patch implements one dummy function from each of them.
