Core db and aristo updates for destructor and tx logic (#1894)
* Disable `TransactionID` related functions from `state_db.nim`

why:
  Functions `getCommittedStorage()` and `updateOriginalRoot()` from
  the `state_db` module are nowhere used. The emulation of a legacy
  `TransactionID` type functionality is administratively expensive to
  provide by `Aristo` (the legacy DB version is only partially
  implemented, anyway).

  As there is no other place where `TransactionID`s are used, they will
  not be provided by the `Aristo` variant of the `CoreDb`. For the
  legacy DB API, nothing will change.

* Fix copyright headers in source code

* Get rid of compiler warning

* Update Aristo code, remove unused `merge()` variant, export `hashify()`

why:
  Adapt to upcoming `CoreDb` wrapper

* Remove synced tx feature from `Aristo`

why:
+ This feature allowed to synchronise transaction methods like begin,
  commit, and rollback for a group of descriptors.
+ The feature is over engineered and not needed for `CoreDb`, neither
  is it complete (some convergence features missing.)

* Add debugging helpers to `Kvt`

also:
  Update database iterator, add count variable yield argument similar
  to `Aristo`.

* Provide optional destructors for `CoreDb` API

why;
  For the upcoming Aristo wrapper, this allows to control when certain
  smart destruction and update can take place. The auto destructor works
  fine in general when the storage/cache strategy is known and acceptable
  when creating descriptors.

* Add update option for `CoreDb` API function `hash()`

why;
  The hash function is typically used to get the state root of the MPT.
  Due to lazy hashing, this might be not available on the `Aristo` DB.
  So the `update` function asks for re-hashing the gurrent state changes
  if needed.

* Update API tracking log mode: `info` => `debug

* Use shared `Kvt` descriptor in new Ledger API

why:
  No need to create a new descriptor all the time
