Add support for explicit CPU affinity via a runner-configurable environment variable (either in the runner configuration, or in the environment of the GHA runner itself). This is useful when running on a host that can't use isolated CPUs (which pyperf automatically detects).
Also undo the changes made by
pyperf system tuneafter the benchmark run. (The system is generally more performant without benchmark tuning, so this matters for other users of the host and for the compile time on a dedicated runner.)
