WorkmanagerExecution class

Shared registry that holds the currently registered background task handler.

One instance is shared by every execution context that runs the compiled dispatcher bundle (the page fallback path, the in-page Web Worker and the Service Worker), so dispatcher code stays identical everywhere.
