Description

To unify the use of bitset filters for different ANN, the filter should use constness on its data type.
Currently only Bruteforce is using const filter: https://github.com/rapidsai/cuvs/blob/branch-24.12/cpp/src/neighbors/detail/knn_brute_force.cuh#L738C54-L738C67
The other indexes don't use const filter.

Research direction

Start with the cited filter usage in cpp/src/neighbors/detail/knn_brute_force.cuh, then inspect the corresponding bitset filter types and usages in the other ANN indexes. The work is done when the ANN filters use consistent constness, with the existing ANN tests passing.
