perf python: Port rw-by-pid from Perl to perf module
Replace the legacy Perl script rw-by-pid.pl with a standalone Python
script in tools/perf/python/rw-by-pid.py using the perf Python module.
Improvements compared to the legacy Perl script:
- Remove the dependency on libperl and Perf::Trace::Util.
- Convert unsigned 32-bit and 64-bit error return values
(0xfffff000..0xffffffff and >= 0x8000000000000000) to negative errnos
so failed read/write syscalls are recorded in the error table rather
than inflating bytes_read / bytes_written.
- Add argparse CLI support (-i/--input) and full type annotations.
Add a shell test
(test_rw_by_pid_python.sh) to verify the standalone script.
