Unified database frontend integration (#1670)
* Nimbus folder environment update

details:
* Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder.
* The `nimbus` program does not compile yet as it needs the updates
  in the parallel `stateless` sub-folder.

* Stateless environment update

details:
* Integrated `CoreDbRef` for the sources in the `stateless` sub-folder.
* The `nimbus` program compiles now.

* Premix environment update

details:
* Integrated `CoreDbRef` for the sources in the `premix` sub-folder.

* Fluffy environment update

details:
* Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder.

* Tools environment update

details:
* Integrated `CoreDbRef` for the sources in the `tools` sub-folder.

* Nodocker environment update

details:
* Integrated `CoreDbRef` for the sources in the
  `hive_integration/nodocker` sub-folder.

* Tests environment update

details:
* Integrated `CoreDbRef` for the sources in the `tests` sub-folder.
* The unit tests compile and run cleanly now.

* Generalise `CoreDbRef` to any `select_backend` supported database

why:
  Generalisation was just missed due to overcoming some compiler oddity
  which was tied to rocksdb for testing.

* Suppress compiler warning for `newChainDB()`

why:
  Warning was added to this function which must be wrapped so that
  any `CatchableError` is re-raised as `Defect`.

* Split off persistent `CoreDbRef` constructor into separate file

why:
  This allows to compile a memory only database version without linking
  the backend library.

* Use memory `CoreDbRef` database by default

detail:
 Persistent DB constructor needs to import `db/core_db/persistent

why:
 Most tests use memory DB anyway. 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)
