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)

use axplicit 127.0.0.1 instead of localhost string on windows, using "localhost" for rpc test is very slow. both pyspec_sim and engine_sim will need more than one hour. while on linux and macos only few minutes.
