dev-python/pygame: enable py3.11, cythonize, adjust deps

For 3.11, meant to wait for next release that was supposed to
happen "soon" and have 3.11 fixes but that was about 3 months
ago and it's blocking adding 3.11 to other packages.

Tests pass on amd64 and tried a few games, afaik only real
issue was that it lacked cythonize which should be done
regardless of a new release.

wrt deps:
* add missing [webp] to test deps (used for 1 test)
* replace deprecated virtual/jpeg
* drop unused smpeg2 (no reference to smpeg in the source I can see)
* drop ancient version checks

Revbump to ~arch as a precaution, albeit unlikely cythonize
is going to cause any trouble.
