perf(core): Fix performance issue in type filter (#9065)

Currently when we do queries like `func(uid: 0x1) @filter(type)`. We retrieve the entire type index. Sometimes, when the index is too big, fetching the index is quite slow. We realised that if we know we only want to check few `uids` are of the same, then we can just check those `uids` directly. Right now we are hard coding the number of `uids` threshold. This could be improved with a more statistical based model, where we figure out how many items does the type index have, how many we need to check.
