Clean up dead code, fix type errors, and add publish workflow

Remove unused _append_ops_call_method, fix _property_data_from_member
call signature, replace sys.version_info guard with hasattr check for
__buffer__ protocol, fix implicit string concatenations, add msgbus
overrides for 4.0-4.4, add conformance tests, and add publish script.
