IndexedDB: Check SSV version when opening database
https://bugs.webkit.org/show_bug.cgi?id=102243
Reviewed by Tony Chang.
Ensure that the data format (SerializedScriptValue) isn't "from the future" when opening
a backing store. Treat an unknown version the same as an unknown schema version.
Chromium-side test at https://codereview.chromium.org/11470013/ (same as other schema version tests)

(WebCore::isSchemaKnown): Check data version as well.
(WebCore::setUpMetadata): Ensure data version is recorded; bump schema version.
* Modules/indexeddb/IDBLevelDBCoding.cpp: Encoding for "DataVersion" global metadata entry.
