This migrates the mostly declarative action mappings in UVREditorInteractor::Init_Implementation into a new GetKnownActionMappings method, which we can poll in order to translate them into an OpenXR action set at the point during early initialization which OpenXR requires them to be registered. This also adds a `bIsAxis` flag to FViewportActionKeyInput, because axis mappings need to be handled differently.
The glue code leveraging this is introduced in a new VirtualScouting plugin, where we'll ultimately migrate the existing code as well (away from VirtualProductionUtilities).

Lightweight instances allow a low memory representation of objects. Instances can be converted into full actors when necessary. Actors can also be reduced down to light weight instances when the full representation is no longer needed.
Hit results now return a handle that may refer to either an actor or lightweight instance.

Refactored FindField into FindUField and FindFProperty to avoid confusion caused by the fact that FindField<UField> will no longer return FProperties.
