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).

This CL ensures that when <vulkan/vulkan.h> is included, the
appropriate VK_USE_PLATFORM_XXX macro is defined to enable the
declaration of platform-specific types and extensions.
Note that for Linux, this requires an xlib_with_undefs.h header
to remove annoying macros that are defined by <X11/X.h> (i.e.
Success, Always, None) and which prevent compilation of other
Dawn sources that use the same symbols as enum value names.
