simplify metamodels

[akphi]

Summary

• Cleanup unnecessary mobx usage in @finos/legend-graph, practically from this moment, the core graph does not use mobx at all; only graph manager does
• For fields of metamodels that we added to support better graph navigation (i.e. owner, parent, etc.) that are not in the actual metamodels, we should prefix them with, _, e.g. _OWNER, _UUID, _PARENT. Also make these fields readonly
• Move buildState out of BasicModel and DependencyManager, pass it in as parameter, move them into GraphManagerState
• Move synthetic enum out of model directories protocols/pure/v1/model, metamodels: these enums are not native to the metamodel, but was added originally for Studio needs
• Refactor to use reference in: LocalMappingPropertyInfo.localMappingPropertyType
• Introduced OptionalSetImplementationReference
