Thread Redaction - Create synthetic threads

In order to merge threads, new thread need to be created. These "fake"
threads will be called synthetic threads. A synthetic thread needs
to have a unique thread id, ensuring no collisions.

Because each CPU will get its own thread, all scheduling events on a
CPU will get moved into that CPU's thread.

The range of PIDs are known (0 to 2 ^ 22), so all synth threads will
be greater than 2 ^ 22.

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.
