[UWP][WindowsMR] - 2018.3 - Memory leak - 1 MB/minute in a UWP VR project due to Spatial Mapping

XR

-

On 2018.3 in a blank project, I exported a UWPPlayer that supports WMR. I'm observing a small leak that aligns with Chris' description. Looks like legacy HoloLensWorldManager code is holding on to a COM reference indefinitely each time we call TryGetSpatialStage which is frequently.

Repro Steps:
1.) Download the repro project
2.) Open the project
3.) Build for HoloLens
4.) Deploy to HoloLens
5.) Attach the profiler
