Port tools/perf/scripts/python/syscall-counts.py to a standalone script in tools/perf/python/ using the perf module. Avoiding the embedded interpreter and per-event dictionary allocation overhead improves execution speed by ~4x: ``` $ perf record -e raw_syscalls:sys_enter -a sleep 1 ... $ time perf script tools/perf/scripts/python/syscall-counts.py perf ... real 0m3.887s user 0m3.578s sys 0m0.308s $ time python3 tools/perf/python/syscall-counts.py perf ... real 0m0.953s user 0m0.905s sys 0m0.048s ``` Additional improvements compared to the legacy script: - Resolve syscall names using perf.syscall_name(id, session.e_machine) instead of host python-audit / Util.py tables, enabling accurate cross-architecture perf.data analysis without external dependencies. - Support both raw_syscalls:sys_enter (sample.id) and individual syscalls:sys_enter_* tracepoints (sample.__syscall_nr / sample.nr), filtering out invalid/corrupt (> 0xffff or negative) syscall numbers. - Add argparse CLI options (-i/--input and optional comm filter). Add a shell test (test_syscall_counts_python.sh) to verify the standalone script. The legacy script and its bin wrapper are retained temporarily during the transition to maintain bisectability and are removed once all scripts are migrated.
