Add perfetto

[Tropicao]

Perfetto is another very nice way of displaying tracing data. Aside from the GUI which seems very user-friendly, perfetto is capable of consuming a wide variety of data sources, supports a "remote" setup, and exposes a powerful filtering system (see Zimuzo Ezeozue's talk @ Embedded Recipes 2025)

• The tool is definitely worth mentioning, at least in the slides, with some basic usage details.
• Bonus: if the setup is not taking too much additional time, it may be worth adding a simple lab to display some traces captured on the target in Perfetto. Maybe the same data from the system-wide tracing lab ?
