perf python: Port intel-pt-events and libxed to perf module

Port intel-pt-events.py and libxed.py from tools/perf/scripts/python/
to standalone modules in tools/perf/python/:
- Refactor intel-pt-events.py into an IntelPTAnalyzer class with full
  type annotations to encapsulate trace state and stashed output.
- Configure instruction trace decoding directly via perf.session's
  itrace option and context_switch callback.
- Dynamically select 32-bit vs 64-bit disassembly mode in libxed.py
  using session.is_64_bit and annotate instructions with source lines
  via sample.srccode().
- Rename methods in libxed.py to snake_case (instruction, set_mode,
  disassemble_one) and remove Python 2 compatibility code.

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