* Refactoring: Unify account_deps and accounts (#17898)
* Changes ThisInvokeContext::get_account() to use accounts instead of pre_accounts.
* Adds explicit keys to accounts to make them symmetric to account_deps.
* Appends account_deps to accounts in transaction loading and removes account_deps everywhere else.
