DirectML Support

[zolrath]

Hello!
Are there any plans for additional backends?
I'd love to see DirectML support to allow it to be used on nvidia/amd cards without requiring installing additional drivers (on Windows/Xbox, at least).

In a similar vein for Apple, CoreML.

Thanks again for your work on this project!
