Draft: WIP: Track librocksdb ABI in symbols file

This is currently WIP as the ABI leaks hundreds of private symbols that should not be there at all and renders ABI tracking via symbols file useless.

Draft status: Filed issue upstream to get assistance: https://github.com/facebook/rocksdb/issues/12929, and upstream filed draft PR at https://github.com/facebook/rocksdb/pull/12944
