Create API review for JS packages with namespace in api extractor model

[praveenkuttappan]

API review JSON input file has namespace model and all public API details are under this namespace model. APIView parser currently ignores namespace and any below members which causes issues for packages that has all it's members under a namespace. For e.g API review for change in PR https://github.com/Azure/azure-sdk-for-js-pr/pull/236/files#diff-6dc05287911739aecce4b2d7cbc4df5699df151c14f032b5a14990cd3f5b2762 is empty.

This PR will process namespace model and its child nodes.

@praveenkuttappan I notice that all tokens under namespace are un-clickable, do you know why? Could we someone fix it?

To say we have a declaration type InferOncologyPhenotypingParameters here

This type is used by post method under interface InferOncologyPhenotyping and when click the reference type InferOncologyPhenotypingParameters we can't jump to relevant declaration.

This one doesn't look like we can resolve with a quick fix in APIView due to the metadata returned by api-extractor itself which is outside the APIView system. I will have a look and talk to someone JS team.
