IDBVersionChangeEvent is already used internally from non-Window
globals, but the constructor wasn't set up to expose the interface
object in worker globals.
Testing: The effort involved in adding a test for this does not seem
worthwhile—we get this for free once we enable the indexeddb preference
while our interfaces.worker.js test is running.

Adds indexeddb support to servo. At the moment heed is being used as the
backend, although this can be swapped out by implementing `KvsEngine`.
This PR adds a thread + a thread pool for Indexeddb related operations.
Also `database_access_task_source` is added for Indexeddb related
operations.
This is a partial rewrite of #25214. (Reopened due to branching issue)
Fixes#6963
