Embedding Perfetto in another project

This doc is WIP, stay tuned

This doc should:

• Contain tech details of the Producer(Endpoint), Consumer(Endpoint) and Service interfaces.
• Explain how they are supposed to be wired up together, with or without using an IPC transport.
• Explain the basic embedder requirements (e.g. TaskRunner)
• Point out the relevant GN targets: //src/tracing, //src/tracing:ipc, //src/ipc.
• Explain the API surface:
  • producer.h
  • consumer.h
  • service.h
• Explain the ABI surface:
  • shared_memory_abi.h
  • IPC's wire protocol (if used)
  • The input config protos
  • The output trace protos
