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.
