Optional accounts cache module for creating genesis (#1897) * Split off `ReadOnlyStateDB` from `AccountStateDB` from `state_db.nim` why: Apart from testing, applications use `ReadOnlyStateDB` as an easy way to access the accounts ledger. This is well supported by the `Aristo` db, but writable mode is only parially supported. The writable AccountStateDB` object for modifying accounts is not used by production code. So, for lecgacy and testing apps, the full support of the previous `AccountStateDB` is now enabled by `import db/state_db/read_write` and the `import db/state_db` provides read-only mode. * Encapsulate `AccountStateDB` as `GenesisLedgerRef` or genesis creation why: `AccountStateDB` has poor support for `Aristo` and is not widely used in favour of `AccountsLedger` (which will be abstracted as `ledger`.) Currently, using other than the `AccountStateDB` ledgers within the `GenesisLedgerRef` wrapper is experimental and test only. Eventually, the wrapper should disappear so that the `Ledger` object (which encapsulates `AccountsCache` and `AccountsLedger`) will prevail. * For the `Ledger`, provide access to raw accounts `MPT` why: This gives to the `CoreDbMptRef` descriptor from the `CoreDb` (which is the legacy version of CoreDxMptRef`.) 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`. The only place where this feature will currently be used is the `genesis.nim` source file. * Fix `Aristo` bugs, missing boundary checks, typos, etc. * Verify root vertex in `MPT` and account constructors why: Was missing so far, in particular the accounts constructor must verify `VertexID(1) * Fix include file

## Read only source, import `state_db/read_write` for full functionality.
##
## Note that the writable mode is only partially supported by the `Aristo`
## backend of `CoreDb` (read-only mode is fully supported.)
