Callback when an event handler has been added to a custom element

We are using message ports to communicate with our logic and are
wrapping the API into a custom element. The issue is that we would
like to call start on a message port only after user has registered an
event handler on the custom element instance. But it seems there is no
way to get a callback when an event handler is added.

So I am suggesting that there should be a callback every time an event
listener is added to a custom element (and possibly one when removed).
