bpo-34523: Support surrogatepass in locale codecs (GH-8995)

Add support for the "surrogatepass" error handler in
PyUnicode_DecodeFSDefault() and PyUnicode_EncodeFSDefault()
for the UTF-8 encoding.

Changes:

* _Py_DecodeUTF8Ex() and _Py_EncodeUTF8Ex() now support the
  surrogatepass error handler (_Py_ERROR_SURROGATEPASS).
* _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() now use
  the _Py_error_handler enum instead of "int surrogateescape" to pass
  the error handler. These functions now return -3 if the error
  handler is unknown.
* Add unit tests on _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx()
  in test_codecs.
* Rename get_error_handler() to _Py_GetErrorHandler() and expose it
  as a private function.
* _freeze_importlib doesn't need config.filesystem_errors="strict"
  workaround anymore.
