DescriptionPrep for landing WK76487
The patch for WebKit 76487 introduces NullType to the WebKit/Chromium WebIDBKey
API to support calls that yield null WebCore::IDBKey pointers, which are subtly
distinct in the spec from "invalid" results (IDBKey of InvalidType).
This patch allows Chromium to build and pass tests with and without that WebKit
patch, although some Indexed DB functionality will be broken until the subsequent
Chromium patch (https://chromiumcodereview.appspot.com/9212038/) lands which
updates test results and updates the IndexedDBKey to match the WebKit semantics.
