Improve performance of the map for large surveys

[andreia-ferreira]

Towards #3866

The performance of large surveys while in the home screen map was bad and could lead to OOM crashes. This was because every LOI outline was handed to the google maps sdk as soon as the survey loaded, just marked as invisible.

This PR changes that so clusterable items are added to the cluster manager but not to the map. Their outlines are created only when the clusterer decides to draw them individually, and released again once they're absorbed back into a cluster.
Additionally, the algorithm of the cluster manager was set as NonHierarchicalViewBasedAlgorithm so that only on-screen features are drawn. This is important especially past the CLUSTERING_ZOOM_THRESHOLD, where all polygons would uncluster and render regardless if they were visible or not
