Migrate failure messages to message_registry.py. This is an attempt to address the issue #6116

According to mypy_primer, this change doesn't affect type check results on a corpus of open source code. ✅

Thanks for the PR, but as noted earlier by others, I don't believe that migrating mypyc errors to using the mypy error registry is worth it. They are independent tools and the vast majority of mypy users will not care about mypyc errors at all.
