Subject: [PATCH] Add undocumented attribute
 multiprocessing.process.BaseProcess._identity (#6041)

A user filed an issue against pytype about this attribute being missing:
https://github.com/google/pytype/issues/1010. I determined its type from
the source code:
https://github.com/python/cpython/blob/3.9/Lib/multiprocessing/process.py.
