Victor Stinner e2ff498cc0 gh-157242: Add byteswriter_check_consistency() (#157723 )

Add byteswriter_check_consistency() to check that the bytes/bytearray
object can be mutated. It is called by all PyBytesWriter functions.

* Add test_thread to PyBytesWriter tests.
* _PyBytes_IsMutable() now checks _PyObject_IsUniquelyReferenced().
* Clarify thread safety in PyBytesWriter documentation.
