AbstractMessageHandler

[tinect]

Please describe the feature you would like to see implemented.

It would be nice, if the old AbstractMessageHandler could be migrated to AsMessageHandler attribute

@tinect @shyim Needed this as well, i've wrote a working rule for it. To be honest, it's 99% generated by gpt-4, but it does work. Could be a starting point :-)

It does the following:

1. Removes extends statement and adds Attribute "AsMessageHandler"
2. Searches for any method name containing "message", implements __invoke method and calls this function
3. Removes getHandledMessages method
4. Adds import for AsMessageHandler if not present

Works in my case, however i am still refactoring and can't say its production-ready :-)
