[Enhancement] Vulkan Surface Creation

[sohaspaces]

Summary

I suggest supporting getting a Vulkan surface handle over a Maui control or a window from a Vulkan instance handle.

API Changes

Enable something like this:

    var surface = (SomeUserMadeHandleStruct)mauiContext.Context.GetVulkanSurface((ulong)someVulkanInstanceHandle);
    //Do whatever with vulkan

so that the GetVulkanSurface function automatically creates from the instance handle.

Intended Use Case

This will make it possible to bind graphics engines, games, or projects to Maui.
