perf python: Port netdev-times to perf module
Port netdev-times.py from tools/perf/scripts/python/ to a standalone
script in tools/perf/python/:
- Refactor the script into a NetDevTimesAnalyzer class with full type
annotations to encapsulate state.
- Collect events via perf.session and sort them in timestamp order
before analysis so multi-CPU TX and RX packet timelines are
reconstructed deterministically.
- Replace custom argument parsing with argparse (-i/--input, --tx,
--rx, --dev, --debug), extract tracepoint fields directly from sample
attributes, and remove Python 2 compatibility artifacts.
Add a shell test (test_netdev_times_python.sh) to verify the standalone
script.
