[#157] Build typedoc reference base on `typeDocName`

Description

Problem: Related to the instance of TypeHasDoc, when there are serveral types with the same name, even if we assign typeDocName differently, typeDocMdReference still refer to the same type name. For example typeDocName: Bar Dog and Baz Dog, they still have typeDocMdReference as the same Dog. The current workaround is to specify customTypeDocMdReference manually.

Solution: build homomorphicTypeDocMdReference which is used by typeDocMdReference as reference to typeDocName, so that we will not have to manually specify customTypeDocMdReference.
