This avoids linking `-lrocksdb` or any other backend by default. * fix `toLegacyBackend()` availability check why: got garbled after memory/persistent split. * Clarify raw access to MPT for snap sync handler why: Logically, `kvt` is not the raw access for the hexary trie (although this holds for the legacy database)

For the new `ledger` API, the accounts are based on the `CoreDxMAccRef` descriptor which uses a particular sub-system for accounts while legacy applications use the `CoreDbPhkRef` equivalent of the `SecureHexaryTrie`.
