refactor(verification): refactor verify_sum [part 2/9]

[glevco]

Depends on #830

Motivation

Currently, TokenCreationTransactionVerifier.verify_sum() has duplicate code from TransactionVerifier.verify_sum(). This PR changes it so it calls the super method instead.

Acceptance Criteria

• Implement TransactionVerifier.get_complete_token_info() and update its verify_sum() to use it.
• Implement TokenCreationTransaction.get_token_info_from_inputs(), overriding the Transaction implementation.
• Update TokenCreationTransaction.verify_sum() to use the new get_complete_token_info().
• No behavior should be changed by this PR.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
