[PAID BOUNTY] [LOCKED] Implement the Direct3D 12 / GDK/GDKX backend

[mrhelmut]

MonoGame needs a Direct3D 12 implementation based on the GDK/GDKX.

📃Full details

This implementation will be the new Windows and Xbox targets, and would replace the current WindowsDX, UWP, and Xbox targets altogether.

"D3D 11 on 12" is not allowed in this context. Therefore, we require an actual D3D12 implementation. The use of DirectXTK is allowed.

@tomspilman has worked on a partial implementation already but couldn't finish it. He's making it available to the applicant in a private repository. The state of this work requires pipeline and memory management to be done.

The Xbox (GDKX) and Windows (GDK) targets are expected to share 99% of the code. We expect that one codebase to be shared between the future WindowsDX and Xbox targets (which should be Windows Store compliant).
