feat: impl StructArray -- create schema, insert, and retrieve data (#42855) 
Ref https://github.com/milvus-io/milvus/issues/42148

https://github.com/milvus-io/milvus/pull/42406 impls the segcore part of
storage for handling with VectorArray.
This PR:
1. impls the go part of storage for VectorArray
2. impls the collection creation with StructArrayField and VectorArray
3. insert and retrieve data from the collection.
