Ryan Schmidt f3812c4df5 GeometryCore: add FSegmentTree3, an AABBTree for 3D line segments. Supports finding Nearest Segment to 3D point, and FindNearestVisibleSegmentHitByRay() which raycasts into a set of boxes based on a "visibility" metric, similar to FGeometrySet3::FindNearestCurveToRay(). ...

Modify FGeometrySet3::FindNearestCurveToRay to use a single visibility metric, instead of branches. The previous code was dependent on the order in which segments were processed, and for the purposes of 3D UI hit testing, did not seem to do any better than the current code.

Add basic tests for FSegmentTree3 queries.
