[IndexedDB] Add a pre-close task to compact the database.
IndexedDB now generates a lot more data during it's readwrite
transactions during API calls like IDBFactory.deleteDatabase. The system
is designed to clean this up over time, but there are possible worst-
case scenarios where the amount of data being written outstrips the
amount of data being compacted/deleted.
This change makes it so all IndexedDB leveldb databases are compacted
when the backing store is closed. This happens after the normal 2 second
grace period. This should:
1) Make IndexedDB's size smaller for all users.
2) Make IndexedDB's performance and usage more consistent
3) Eliminate the case where uncompacted data from deleting databases is
hogging up the disk.
