cts: attempt to deflake TracedPerfCtsTest

Instead of relying on traced_probes happening to run at the time of
periodic sampling, sample all context switches and let the profiler
filter that down to traced_probes.

Slightly concerned about pressure on kernel perf buffers on slow
emulators and whatnot, but imo the pragmatic approach here is to submit
and observe.

Perfetto - System profiling, app tracing and trace analysis

Perfetto is a production-grade open-source stack for performance instrumentation and trace analysis. It offers services and libraries and for recording system-level and app-level traces, native + java heap profiling, a library for analyzing traces using SQL and a web-based UI to visualize and explore multi-GB traces.

See https://perfetto.dev/docs or the /docs/ directory for documentation.
