Misc SurfaceData Optimizations (#7299)
* 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*. (#7216)
* 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.

SurfaceData cleanups to prepare for bulk APIs (#7166)
* Initial cleanup of GetSurfacePointsFromRegion in prep for bulk API support.
* Removed the generated lookup point from the output structure. Nothing was using it, and by keeping it separate, I can pass it in as a list of points that can be passed throughout the terrain, gradient, and surface data APIs.
* Clarified on the SurfaceProvider bus that GetSurfacePoints() only gets valid XY values on the inPosition.
* Simplified the TerrainSurfaceDataSystemComponent implementation a bit.  The EnumerateHandlers() and the terrain Aabb checks were overkill. Also, the terrain Aabb check assumed that the Z value on the inPosition was valid, which it isn't always.
