Test MacOs Surface Support

[ncharlton02]

Only windows/linux has been tested supported natively. For now on Mac the window surface is set to zero which works on Windows 10, but may not on Mac.

For full support, Macos specific code is needed to get Glfw to communicate with Wgpu (and I don't own a mac ☹️ )

Areas that need written:

• GlfwHandler.getOsWindowHandle()
• Window.Init()

So I just ran a test on Windows, and if a surface of zero is passed in, then wgpu works fine. I am not sure if this will work or if its a windows only feature but for now Kgpu will just return a surface of zero for non-tested platforms

I have edited the original post to reflect this change
