[issue12281] bytes.decode('mbcs', 'ignore') does replace undecodable bytes on Windows Vista or later

Yes, we can use an error handler specific to the mbcs codec, but I would prefer to not introduce special error handlers.

For os.fsencode(), we can keep it unchanged, or add an optional "flags" argument to codecs.mbcs_decode().

codecs.code_page_encode() and codecs.code_page_decode() are required for unit tests. If you don't want to add new public (C and Python) functions, we may add them to _testcapi.
