Trace Redaction - Create shared filter ftrace events primitive

There are multiple primitives that filter conditional drop ftrace
events. When these are individual primitives, each packet is
deserialized and reserialized N times (where N is the number of
filter primitives).

To reduce the number of reserializations to 1, this CL introduces
a primitive that accepts filters. Each event is tested against
the filters and if any filter say "drop event", the event is
dropped and all later filters are skipped.

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.
