[improve][txn] Allow transaction owners to abort their own transactions via the abortTransaction admin API

[hrzzzz]

Motivation

PIP-325 (https://github.com/apache/pulsar/pull/21731) states that a transaction owner should be able to use the abortTransaction admin API to abort their own transactions, and that a super user can abort any transaction. However, the current implementation does not permit a transaction owner to access the abortTransaction admin API to abort their own transactions. This PR aims to resolve this issue.
