rust-cpython: add safe wrapper representing shared data borrowed from PyObject

PySharedRef is a tempoary wrapper around PySharedRefCell. It provides safe
functions for each shared data. $shared_accessor implements a safe method
to construct PySharedRefCell.

This allows us to add more than once PySharedRefCell to a Python object.
