Cache YangModuleInfo type name

Analysis of a heap dump shows we are creating a number of instances
pointing to the same type for the purposes of having the QNAME constant.

As we have the context in which we are creating YangModuleInfo,
instantiate a primitive cache to de-duplicate these definitions.
