feat(structuredProperties) Add new settings aspect plus graphql changes for structured props

[chriscollins3456]

This PR brings out the new structuredPropertySettings aspect that will allow us to set specific display preferences on structured properties for showing them on assets in the UI. This also updates all of the graphql resolvers for this new settings aspect as well as the graphql schema. Additionally, tests have been added to reflect all of these changes in the resolvers and utils classes.

There are some other miscellaneous improvements to structured properties as well such as:

• add validation in our graphql resolver that the ID and the qualified name are the same (needed based on assumptions we make in our ES mapping code)
• adds backend support for returning an associated urn with a structured property which will enable us to handle siblings much better in the UI.
