[media] cec: filter invalid messages

As per the CEC specification:

- CEC messages with a too-small payload should be ignored.
- Broadcast messages that are only allowed as directed messages
  should be ignored.
- Directed messages that are only allowed as broadcast messages
  should be ignored.

Implement this in the core CEC framework.
