IndexedDBClient was a WorkerClient and it provided AllowIndexedDB().
IDBFactory extracted an IndexedDBClient from execution context to
call AllowIndexedDB(). However this was an unnecessary abstraction
and we can directly implement AllowIndexedDB() in IDBFactory.
This CL removes IndexedDBClient to remove the abstraction.
This eliminates creating a GarbageCollection object.

This CL doesn't have behavioral changes.
