[BE][Easy] enable ruff rule PIE790: unnecessary pass statement (#133200)

This PR removes unnecessary `pass` statement. This is semanticly safe because the bytecode for the Python code does not change.

Note that if there is a docstring in the function, a empty function does not need a `pass` statement as placeholder.
