[Feature]: OpenXR passthrough to host OS

[glorantq]

Is your feature request related to a problem?

With the use of Monado VR gaming on a Mac is possible, in native applications. Currently though, Wine does not support OpenXR out of the box, meaning Windows games can't be played in VR.

Describe the solution you'd like

To my knowledge, since Wine doesn't support OpenXR by itself, Valve has written a runtime for it in their Proton to just pass through the API calls to the host OS. An implementation like this would also work here on macOS, since we can get OpenXR working in native Mac applications.

Anything else?
