        [WebGPU] Add WGSLUnitTests XCTest target for WebGPU
        https://bugs.webkit.org/show_bug.cgi?id=233227

        Reviewed by Robin Morisset.

        For now, this new target isn't hooked up to any automated testing - it's just a local target which developers can run.

        * Configurations/WGSLUnitTests.xcconfig: Added.
        * WGSLUnitTests/WGSLUnitTests.mm: Added.

        [WebGPU] Add necessary additions to WebGPU.framework
        https://bugs.webkit.org/show_bug.cgi?id=233091

        Reviewed by Dean Jackson.

        WebGPU.framework's header file is lagging a bit behind the official WebGPU API.
        This updates a companion header, WebGPUExt.h, with the necessary additions.
        I don't want to modify the primary header, WebGPU.h, because it's shared among
        multiple projects, so coordination is necessary to modify it.

        [WebGPU] Stub out methods in WebGPU.framework

        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.
