tp: implement tree partitioning by group algorithm

This CL implements an algorithm to partition tree into a forest based
on a grouping key and preserving the structure of the original tree.

This algorithm will be used to prevent double-counting for heap graphs
and also might be generally useful in the future for critical path
work.

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.
