Cleaned up sculpt code to store lists of `PBVHNodes` with
`blender::Vector` instead of simple pointer arrays. This is much
simpler and eliminates memory leaks caused by forgetting to free
the result of `BKE_pbvh_search_gather`.
Notes:
* `BKE_pbvh_search_gather` is now `blender::pbvh::search_gather`.
* `FilterCache` and `ExpandCache` have ownership over their .nodes
members; as a result they're no longer pure C structs and
are allocated with `MEM_new`/`MEM_delete`.
* The word 'totnode' no longer occurs anywhere in
`source/blender/editors/sculpt_paint`
Todo (not for this PR): create a new properly C++ task API for sculpt
(with lambdas) and use it for brushes.
