zach brockway 8c306be3fb Virtual Scouting: GetHMDDeviceType backward compatibility under OpenXR. ...

Fixes several bugs sharing the same root cause, where code/blueprints were attempting to branch on UVREditorMode::GetHMDDeviceType() or UVREditorInteractor::GetHMDDeviceType(). These calls previously returned the result of IXRTrackingSystem::GetSystemName(), and the call sites were only set up to handle "OculusHMD" or "SteamVR," and were now seeing "OpenXR". Instead, we now return one of those legacy plugin names, depending on the current OpenXR hand controller interaction profile. Longer term, we will want to revisit each of these decision points individually, and take into account support for future unknown XR devices.

An alternative subclass of UVREditorMode can now be configured in the editor settings alongside the interactor and teleporter classes, and a new UVirtualScoutingMode subclass splits the mode entry into two phases. This is necessary because OpenXR may not return the correct interaction profile for several frames after the OpenXR session / stereo rendering has started, and we need to defer creation of the interactors, etc.
