* First pass at encapsulating SurfacePointList.
The biggest challenge in optimizing SurfacePointList(s) usage is the overall memory management associated with it. There are M surface points with N surface mask entries created for every input point, which leads to a lot of container reallocation and memory shuffling when processing multiple input points. By encapsulating the list, it should become easier to preallocate the entries, as well as keep "helper data" around for managing the bookkeeping to associate the input points with the output points.

* Misc SurfaceData Optimizations.
This includes a few different optimizations found while trying to make the bulk query APIs faster:
* Switches mutexes over to shared_lock to optimize for the multi-reader-single-writer pattern
* Surface provider point creation now uses a pre-created set of masks to initialize with, and uses std::move() to move the created point into the output list instead of copying it.
* Splits CombineSortAndFilterNeightboringPoints so that the FilterPoints() can occur separately and efficiently with erase/remove_if, and avoids making a copy of the output points.
* Optimized SurfaceDataShapeComponent::ModifySurfacePoints
* Fixed potential bug where the sort wasn't stable since it only compared the Z value, and could have produced unexpected results for differing points with the exact same Z value.
* Fixed up a couple small bugs and missing checks in the unit tests

* Add benchmarks and unit tests for GetSurfacePoints*.
The benchmarks are very enlightening - the existing implementation of GetSurfacePointsFromRegion (and GetSurfacePointsFromList) is currently measurably *slower* than just calling GetSurfacePoints() many times in a loop. This is due to all of the extra allocation overhead that's currently happening with the way these data structures are built.
