win32mbcs: use str for encoding value

This was reported to the TortoiseHg tracker as:
https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5980

It doesn't look like we have any tests for this extension, but the explicit
type hints are enough to convince pytype that the module level `_encoding` attr
is str.  The `encode()` and `decode()` methods are too complex to add type hints
for them.
