KAFKA-19140 ConnectAssignor#performAssignment parameter can be replace to ConnectProtocolCompatibility

[m1a2st]

The protocol type; for Connect assignors this is "eager", "compatible",
or "sessioned"

Since ConnectAssignor is an interface and the protocol parameter is
restricted to "eager", "compatible", or "sessioned", it aligns with the
existing ConnectProtocolCompatibility enum. Therefore, we can update the
code to use ConnectProtocolCompatibility directly.
