Reland Migrate to python 3.11 from 3.8

Original CL: https://chromium-review.googlesource.com/c/chromium/src/+/5872818
was reverted and was not able to create an actual reland because of
rebase merge failure with "create reland" button.

Previous CL was reverted from failing:
chromeos-jacuzzi-rel
chromeos-octopus-rel

This is from a incompatibility in aioquic, which is now fixed with
an update to aioquick 1.2 (and its supporting libraries) as well as
adding python and permission changes to chromeos.

crrev.com/5904256
crrev.com/5904734

and some internal changes.

The webtransport_h3_server.py file has to be changed here with the
vpython change, and then wpt can be rolled. The change is already
in the wpt repo, but has been manually excluded in the roll.
