upgrade itertools to 0.12
upgrade av1-grain, av-metrics, cargo-c, cargo, debcargo, gping, ratatui, gstreamer, lalrpop, malachite-base, predicates, prost-build, prost-derive, rav1e, rustpython-compiler-core, shrinkwraprs, sqlformat, zxcvbn, arc-swap, gstreamer-audio, gstreamer-video, itertools-num, libcst, plotters, serial_test to use itertools 0.12
Known problems:
- Jonas packages: criterion and test-case is also affected and there is some test-dependencies where these packages test-depends on criterion.
- indexmap seems to be in the process of an upgrade to 2.1 so I haven't touched that one.
