feat(alm): add alm.clear() method

[FaberVitale]

Description

Adds the following apis

• alm.clear(): unsubscribes all listeners, cancels running listeners and tasks.
• clearListenerMiddlewareAction: an action creator whose actions trigger alm.clear().

Context: #1648 (comment)

SSR

I believe that this method can be very useful in SSR, because it provides a simple way to clean up all listeners that are still subscribed or running after rendering the page.

Should we add this as an action creator, too?

Yeah.

I was worried about weird interactions but we do not notify addListener and removeListener to the listeners. 👍

also very interested in any other improvements to the "remove" APIs and behavior you can think of, per #1648 (reply in thread)
