Coredb use stackable api for aristo backend (#2060)
* Aristo/Kvt: Provide function hooks APIs

why:
  These APIs can be used for installing tracers, profiling functoinality,
  and other niceties on the databases.

* Aristo: Provide optional API profiling

details:
  It basically is a re-implementation of the `CoreDb` profiling
  implementation

* Kvt: Provide optional API profiling similar to `Aristo`

* CoreDb: Re-implementing profiling using `aristo_profile`

* Ledger: Re-implementing profiling using `aristo_profile`

* CoreDb: Update unit tests for maintainability

* update copyright dates

The file accounts_cache.nim has been relocated

Background

The new LedgerRef module unifies different implementations of the accounts_cache. It is intended to be used as new base method for all of the AccountsCache implementations. Only constructors differ, depending on the implementation.

This was needed to accomodate for different CoreDb API paradigms. While the overloaded legacy AccountsCache implementation is just a closure based wrapper around the accounts_cache module, the overloaded AccountsLedgerRef is a closure based wrapper around the accounts_ledger module with the new CoreDb API returning Result[] values and saparating the meaning of trie root hash and trie root reference.

This allows to use the legacy hexary database (with the new CoreDb API) as well as the Aristo database (only supported on new API.)

Instructions

import accounts_cache import ledger preferred method,
AccountsCache.init(..) AccountsCache.init(..) wraps AccountsCache
methods
or
import ledger/accounts_cache stay with legacy
AccountsCache.init(..) version of

The constructor decides which CoreDb API is to be used
