Safari's IndexedDB data may not be deserialized correctly after system
upgrades

Reviewed by Mark Lam.
To fix rdar://119834827, we introduce version 12.1 to SerializeScriptValue,
which changed the terminator of the indexed
property section in array compared to version 12. To make sure deserializer
knows to deserialize version 12.1, we encode
the minor version in the highest 8 bits of version number. We keep the lowest
24 bit as major version number for
backward compatibility (the previously stored 32-bit major version number can
be intepreted as major version with minor
version 0).
