Replace Rocksdb with LMDB

[Geometer1729]

• [x] Implement module
• [x] make create migrate any existing rocksdb data
• [ ] Debug/Pass CI
• [ ] Review

Debugging: It seemed like set_batch was breaking things but it turned out that the rocksdb fold methods were broken which was causing the data to appear to disagree. https://app.zenhub.com/workspaces/protocol-eng-663019a2b7c02c03cd737a1a/issues/gh/minaprotocol/mina/15838 Once that was fixed I noticed to_alist was backwards for rocksdb so I fixed my code to replicate that.
