WebKit2: Add additional API for managing databases
https://bugs.webkit.org/show_bug.cgi?id=51629

Reviewed by Anders Carlsson.

- Adds WKDatabaseManagerGetDatabasesByOrigin, which asynchronously returns
  an array of dictionaries containing details about each origin using
  databases and details about each database. Keys were added for accessing
  the data in the dictionaries.
- Adds WKDatabaseManagerDeleteDatabasesWithNameForOrigin to delete a database
  with a specific identifier.
- Adds WKDatabaseManagerSetQuotaForOrigin to set the quota for an origin.
