Specification for dirty event, dirtyPayload(), and `XXXPayloadDirty() to puppet abstraction, puppet implementation, puppet server, and puppet client.

[huan]

Specification

1. If the low-level puppet wants to dirty a payload, emit a dirty event
2. If the high-level puppet wants to dirty a payload, call dirtyPayload() method, what it does (and only does) is to make the low-level puppet emit a dirty event.
3. every puppet should listen to the dirty payload, and call XXXPayloadDirty(id) to dirty a specific payload.

Huan(202109): That's all, I hope the above 3 points can make it clear.
