This is another step to implement webgpu.h swapchains, Surface is essentially a union type of all the types of windows that can be used to create swapchains. Changes to allow implementing wgpu::Surface and test its creation are: - Add GLFWUtils.cpp/.h/_metal.mm that contains helpers used to use WebGPU with GLFW. This deprecates BackendBinding.h that will be removed when the NXT swapchain is removed. - Add a `dawn_use_x11` GN variable to factor all the places in BUILD.gn where we checked whether we should use X11. - Add a `supports_glfw_for_windowing` GN variable in the main BUILD.gn file to control which configuration tests and samples using GLFW can be built. - Add a ObjCUtils.h to contain some ObjC functionality that we'd need in files that otherwise would be C++ (so that they can be compiled on all platforms).
