Build for Python 3.11 as well

On Windows and OS X, this simply adds a bunch of extra builds. On Linux,
I'm also bumping the manylinux tag because Python 3.11 is newer than the
distro in question. This means that there will be no builds for "new
Python on old distros" because one has to draw a line somewhere.
Effectively, wheels for Linux Python 3.11 will therefore require glibc
2.35.
