IndexedDB: Run cursor-prefetch webkit layout test as ui test.

The test exercises a bug that is only triggered when run in multi-process chromium.  The patch in https://bugs.webkit.org/show_bug.cgi?id=75596 has to be committed and rolled before this change can be committed.

This ui test will eventually run all of the IDB layout tests.
