OpenXR Toolkit Crashes on DX12/Integrate FR Into UEVR

[m8t88]

Is your feature request related to a problem? Please describe.
The OpenXR Toolkit has a generic functionality to allow fixed foveated rendering to improve performance in games. The current app OpenXR Toolkit 1.3.2 seems not to be compatible with UEVR. The issue might be that two different toolkits are trying to access the same APIs (just a hunch)

Describe the solution you'd like
Either enable UEVR to run in parallel with OpenXR Toolkit or (preferred) have native fixed foveated rending support in UEVR. This could help a lot to improve performance in all VR games.

Describe alternatives you've considered
Disable OpenXR Toolkit and reduce the OpenXR overall resolution in UEVR. Noticeable reductionin picture quality though.

Pinned and renamed the issue for further visibility so I don't get additional issues about this
