Trace Redaction - Broadphase Filtering

Previously, whole packets were dropped when they did not pass the
allow-list check. This meant important information abount
packet-to-packet timing and data-loss was removed.

This CL changes all broadphase filtering code to use a mask. This
is applied at the packet level and at the ftrace event packet.

This has shown important differences when viewing traces as additional
CPU time used by the target process increases.

A side effect of this change is non-target timeline information has
also showed up. An additional change will be needed to address the
timeline information.

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.
