Improve performance of the index selector

[V0ldek]

Short description

Improved the access patterns for array index selectors.

First, member and array transitions are now in separate smallvec arrays, so we can always look only at the relevant array transitions.

Second, properties like "has array transition" or "can accept via array transition" are now cached during minimize as StateAttributes.

Overall on chirop@lille this gives from 7% to 12% thpt increase on most of the main benchmark.
See full bench report at the bottom.

Benchmark report

There is a weird regression on ./data/twitter/twitter.json_user_mentions_indices/rsonpath_mmap_count which should be investigated as part of #151. However, the change looks reasonably beneficial on all other benches.
