Port task-analyzer.py from tools/perf/scripts/python/ to a standalone
script in tools/perf/python/ refactored into a class-based architecture.
Improvements compared to the legacy script:
- Support both offline perf.data file analysis (using perf.session) and
live trace capture (using evlist.read_on_cpu), accessing
sched:sched_switch tracepoint fields directly from sample objects.
- Automatically disable ANSI terminal color escape sequences when --csv
or --csv-summary is enabled so CSV column headers ('Comm,',
'Time Out-Out,', etc.) are never polluted by color codes when running
interactively on a TTY (e.g. as root).
- Sanitize non-printable characters and leading CSV formula characters
(=, +, -, @) in task comm strings.
- Emit a one-time warning to stderr if sched:sched_switch samples are
missing tracepoint fields (such as when recorded without libtraceevent
support).
Update test_task_analyzer.sh to invoke the standalone script.
