[Serialization] Serialize Differentiability WT index sorted

Browse Source 
When there are sil_property and sil_differentiability_witness at once,
serialized file couldn't be deserialized because it's index table is
serialized un-sortedly but deserializer assumes that contents of table
index are sorted.

This patch fixes the un-sorted serialization and adds test case to
ensure that table index contents can be deserialized
