Split AsyncAPIs into component APIs

[DiamondJoseph]

i.e. WorkerStatus API, Bluesky Document API etc.

Allows for injestion in Backstage spec.providesApis, spec.consumesApis more neatly and elegantly for System purposes.

Possibly contradicts the plan to collapse all events into one topic?

Doesn't look like Channel has to be unique(ly named) among AsyncAPIs.
