* 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.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Encapsulate surface point creation and separate EnumeratePoints out from modifications. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Start removing SurfacePoint from the exposed API. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Changed SurfacePointList to split out the surface point storage to allow for span<> usage over time. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Removed entity id Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Removed SurfacePoint from SurfaceData, changed all remaining uses to AzFramework::SurfaceData::SurfacePoint. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Encapsulated SurfaceTagWeightMap and renamed to SurfaceTagWeights. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Fixed make file. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Better commenting and parameter naming. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Renamed methods to be more descriptive. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>
