In preparation for a prototype Terrain Gem to get submitted, there are a few changes that are needed outside of the Terrain Gem as well: The TerrainDataNotificationBus lives in AzFramework/Terrain, and needed to be extended to contain an optional OnTerrainDataChanged event to notify other systems when a terrain region has changed. The HeightmapUpdateNotificationBus was removed, as this was a legacy file from the old already-removed terrain system. The EditorWrappedComponentBase<> wrapper received a small optimization to ensure that ConfigurationChanged() is only called when the value of visibility actually changes. With prefabs, it appears that sometimes OnEntityVisibilityChanged could be called multiple times in a row with the same visibility value. The TerrainSurfaceDataSystemComponent was updated to use the correct busses, and is ready to be moved to the Terrain Gem in a subsequent PR.
