Merging //UE4/Partner-Microsoft-XR to Release-4.23 (//UE4/Release-4.23) Change: 7668425
Remove Eye Tracking Origin offset in favor of changing the tracking origin at runtime in the game-level if necessary. The HoloLens camera should be eye tracking and content should be correctly rendered relative to the camera's starting position.
Implement HasValidTrackingPosition()
Update ipd every frame now that calibration can be triggered at any time
Merging //UE4/Partner-Microsoft-XR to Release-4.23 (//UE4/Release-4.23) Change: 8512891

-A custom build step now generates the header MixedRealityInteropBuildInfo.h which has a define like "#define WINDOWS_MIXED_REALITY_INTEROP__WINDOWS_TARGET_PLATFORM_VERSION 10.0.18362.0" with the version being whatever $WindowsTargetPlatformVersion is for the MixedRelaityInterop project build. This will allow the UE4 build process to respond to the WindowsSDK that the interop was built with.
-WindowsMixedRealityAvailability.h sets #defines based on sdk and platform so that we can enable or disable features in UE4.
-Fixed hand tracking so that it does not rely on a motion contrller pumping the hand traking data update of the interop.
-Gesture callbacks now feed a queue which dispatches the controller events from the game thread.
-Turned some asserts that could be triggered by dubious blueprint setup into warnings.
-The HololensAR plugin is now functional when remoting and on WMR headsets. HololensRemoting now supports all the AR features, except the passthrough camera which is currently unsupported by microsoft. WMR Supports only anchors and the anchor store.

-Hand merging from Dev-vr
-Was crashing due to continued use of a structure which had been MoveTemp-ed to another.
-Now we copy that data before MoveTemp.
-Rearranged the function a bit to get everything into blocks of similar update frequency.
