typing: restore `encoding.encoding` and `encoding.encodingmode` to bytes

Somewhere between hg 3dbc7b1ecaba and hg 8e3f6b5bf720, pytype determined the
signature of these fields changed from `bytes` to `Any`.  Not sure why- the type
of `environ` then and now is: `Union[WindowsEnviron, Dict[bytes, bytes], os._Environ[bytes]]`
That said, PyCharm wasn't able to figure out the type of `environ`, and the
`WindowsEnviron` class extends `MutableMapping` without specifying bytes for the
key and value types in py3.9.  But that's not changed in my setup, so I can't
explain it.
