When deleting an IndexedDatabase file, also invalidate any currently open handles to that database

In https://bugs.webkit.org/show_bug.cgi?id=135346 we're making the WKOriginDataManager API actually delete IndexedDatabase files.

But any web page that happens to have an open handle to those files will:
    - For read-only operations, they will continue functioning as normal on the unlinked file.
    - For write operations, they will start producing errors as SQLite notices the missing backing store.

The handles should be explicitly invalidated with errors sent back to the WebProcess(es)
