GEODE-5917: Modified instanceof to check for CachedDeserializable instead of VMCachedDeserializable

> Gfsh query results show a mix of PdxInstances and PreferBytesCachedDeserializables with read-serialized=true
> A gfsh query on a partitioned region with pdx read-serialized=true shows results like:
