[issue18509] CJK decoders should return MBERR_EXCEPTION on PyUnicodeWriter error

[STINNER Victor]

New submission from STINNER Victor:

I modified CJK codecs to reuse the new PyUnicodeWriter API (to use the PEP 393 instead of Py_UNICODE*). The problem is that PyUnicodeWriter error is not handled correctly: the decoder should return MBERR_EXCEPTION, whereas the error is not handled at all currently.

I found this issue while working on issue #18408, using the pyfailmalloc tool to inject faults (memory allocation error).
