Add WebKit1 API to view and delete local storage
https://bugs.webkit.org/show_bug.cgi?id=51878

Created StorageTracker as a central point for tracking and deleting LocalStorage per origin.
StorageTracker maintains its own database of origin identifiers and backing db paths,
and this allows it to contain more relational data in the future, like variable quotas per origin.

On initialization, StorageTracker syncs its database with LocalStorage files on disk. It adds
an origin entry when StorageAreaSync performs a first sync for an origin.

All StorageTracker file operations are performed on one background thread with a task queue.
