Exposing Native GPU Handles

Child of #9289

Intent

Exposing device, instance and queue handles to the game.

Motivation

These native GPU handles are necessary for building OpenXR integration. This is my main use case, as it was proposed here: #9289

In addition to that, this allows people to use other libraries to render to MonoGame's target surface as well: https://github.com/vchelaru/SkiaGameRendering
