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.

Test that raising an exception in the release function doesn't cause the lock to choke

  >     l = repo._lock(repo.vfs, b'testlock', False, unlock, None, b'test lock')
  >     return l
