Add aggregation function EXPERIMENTAL_PPROF

traceconv currently generates a pprof profile for all samples in a
trace. For some analysis we might be interested in only looking at
certain samples (e.g. those that intersect a given slice). This new
function allows to generate a pprof profile for a given set of samples.

E.g. To get a profile per thread

SELECT tid, EXPERIMENTAL_PPROF(callsite_id)
FROM perf_sample
JOIN thread USING (utid)
GROUP BY tid

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.
