UDAFs do not respect the Configurable interface

[MichaelDrogalis]

Describe the bug

Version: 0.10.0, related to #5737

The docs describe that a UDF can be made configurable with external parameters by implementing the Configurable interface. This works as described for scalar functions. But it doesn't work for UDAFs. The configure() method is silently ignored. This might be a bit worse than #5737 because UDAF factories expect to return a Udaf or TableUdaf. Because Java doesn't support type unions, we might need to jump through some hoops to get ksqlDB to realize which UDAFs are configurable and which are not.

Either way, this behavior should also function for UDAFs.
