Description

When we introduced SystemContentBlock support in #1141, we accidentally broke users who were updating the system_prompt after agent initialization. This is because we were making a copy of the prompt and storing it in _system_prompt_content.

To fix this in a backwards compatible way, we create a system_prompt setter and getter to make sure the values are synchronized.
