Ian Rogers eeb70645a8 perf python: Port event_analyzing_sample to perf module 
Port event_analyzing_sample.py to a standalone script in
tools/perf/python/ using the perf module and standard library sqlite3
module.

Improvements compared to the legacy script:
- Encapsulate database state in a _DB container instead of mutating
  module-level globals, and ensure temporary SQLite database files are
  cleaned up on exit.
- Add argparse CLI options (-i/--input and -d/--db) while preserving
  PerfEvent, PebsEvent, and PebsNHM binary raw_buf unpacking and
  symbol/DSO histogram reporting.
- Remove Python 2 compatibility code and add type annotations.

Add a shell test (test_event_analyzing_sample_python.sh) to verify the
standalone script.
