feat: add Read request to retrieve the details of the Collection

[chungquantin]

Originally, the #432 introduces a read Collection to query the optional CollectionDetails. However, this requires adding the CollectionDetails type on the contract library, increasing the size of the contract. Another reason why the approach is not efficient is, there are Read requests TotalSupply and OwnerOf to retrieve the fields items and owner of the CollectionDetails struct.

One possible approach is to introduce three additional reads to query other fields of the collection:

• CollectionItemConfigs
• CollectionItemMetadatas
• CollectionAttributes
