refactor(typings): improve emit types (#4817)

This commit fixes several issues with emit types:

- calling `emit()` without calling `timeout()` first is now only available for events without acknowledgement
- calling `emit()` after calling `timeout()` is now only available for events with an acknowledgement
- calling `emitWithAck()` is now only available for events with an acknowledgement
- `timeout()` must be called before calling `emitWithAck()`
