perf python: Port check-perf-trace to perf module
Port check-perf-trace.py to a standalone script in tools/perf/python/
using the perf module directly.
Improvements compared to the legacy script:
- Access tracepoint fields directly as attributes on perf.sample_event
instead of per-event dictionaries and legacy Perf-Trace-Util helpers.
- Decode symbolic flag and enum masks for irq:softirq_entry and
kmem:kmalloc directly in Python and add -i/--input CLI support via
argparse.
- Add full type annotations and clean up Python 2 idioms.
Add a shell test (test_check_perf_trace_python.sh) to verify the
standalone script.
