Luca Greco fa6ffb7af2 Bug 1682632 - part2: Extension API request handling. r=baku,mixedpuppy
New XPCOM idl interfaces to define the components used to:
- represent an API request (call to API methods, add/remove API event listener,
  get the value of an API property getter)
- define the API request handler defined by privileged JS code running on the
  main thread

New ExtensionAPIBase shared stub methods and helper methods to create and forward
the API requests from the worker to the main thread and translate the results
got from the API request handler in the value to return or resolve (or the errors
to be raised) to the extension code running on the worker thread.

Depends on D80604
