Migrate PCLI classes working with the state to hedera-app module

[imalygin]

The following PCLI commands work with the state:

• StateEditorCommand
• GenesisPlatformStateCommand
• CompareStatesCommand
• ValidateAddressBookStateCommand

Unfortunately, these commands are not functional at the moment because they all use SignedStateFileReader#readStateFile. Any attempt to run the command against the existing application state will result in a ClassNotFoundException, as it won't be able to find the corresponding state class by a class ID and deserialize it since the class is defined at the application level.

To fix this issue, the aforementioned commands and the classes working with the state should be migrated to the hedera-app module.

To find an example of a command at the application level to use as a reference, do the following:

• Run git checkout b573c31b5024349fe3a1f64becbfaaa67144bd4.
• Consider AccountBalanceCommand and AccountBalanceSignCommand.
