Remove typing.io and typing.re

[srittau]

As discussed in #82472 and mentioned in the documentation, the typing.io and typing.re submodules are scheduled for removal in Python 3.12. They've been deprecated since Python 3.8.

I'm preparing a PR.

(Side note: There doesn't seem to be a matching issue template for this kind of issue.)

@srittau Bedevere the bot has this feature disabled for a while. python/bedevere#430 will enable it back after merging (i believe it's on feedback gathering stage).

Interestingly, importing from typing.re or typing.io never worked at type check time. Since typeshed doesn't include those namespaces, when --ignore-missing-imports is used, any imports from those namespaces were silently assumed to by Any.
