refactor: remove behavior protocol syntax

[lars-reimann]

Summary of Changes

• Remove the syntax for behavior protocols
• We can add this (and the actual validation) again once we have more use cases for behavior protocols. For now they only seem to be useful to ensure that predict/transform can only be used on fitted models/transformers.
