[web-db] migrate entire redux-persist storage to SQLite

Summary:
This code will switch redux-persist storage to this based on encrypted SQLite.

However, to make a gentle switch we need to look to old storage and migrate the data if possible.

Depends on D7667

Test Plan:

1. Enable this code
2. Check is persisted content is not missing but stored in SQLite
3. Data from old storage should be removed.
