Access account information without triggering changes

[FlorianHuc]

Description

In order to generate traces of the EVM, the arithmetization requires access to the accounts.

Current available method:

 MutableAccount getAccount(Address address);

gives the required information, but the implementation in the abstractWolrdUpdated as a side effect adds it to the updatedAccounts list which ends in state modification later during the processing. To avoid this unwanted modification, we need a method returning the same information without the side effect.

Acceptance Criteria

• new method available to get data without tracking the account.
