Adjacency_matrix aggregation optimisation. (#46257) (#46315)
Avoid pre-allocating ((N * N) - N) / 2 “BitsIntersector” objects given N filters.
Most adjacency matrices will be sparse and we typically don’t need to allocate all of these objects - can save a lot of allocations when the number of filters is high.

Closes #46212
