H-2927: Pass metadata alongside properties to Graph SDK

[TimDiekmann]

🌟 What is the purpose of this PR?

The Graph SDK currently merges properties and their metadata but metadata are almost never passed. As we're going to make dataTypeId required, this moves out the compound object generation and requires the full object to be passed.
