✨ Add ExceptionHandler component

[MFA-X-AI]

Description

This PR adds ExceptionHandler component. Useful for workflows that might hit an exception. This component allows users to handle it gracefully. Attach the main execution to its body branch, and if it hits an exception it will continue on the exception branch, with the exception message. It will then continue with the main execution whether it hits the exception or not.
