perf python: Port rw-by-file from Perl to perf module
Replace the legacy Perl script rw-by-file.pl with a standalone Python
script in tools/perf/python/rw-by-file.py using the perf Python module.
Improvements compared to the legacy Perl script:
- Remove the dependency on libperl and Perf::Trace::Util.
- Encapsulate per-file-descriptor read/write byte and call count
aggregation in an RwByFile class using perf.session and resolve thread
command names via session.find_thread(pid, sample_tid).
- Add argparse CLI support (-i/--input and target program filter) and
full type annotations.
Add a shell test
(test_rw_by_file_python.sh) to verify the standalone script.
