Pass correct request body in materialize provider

[RemindD]

Fix https://github.com/eclipse-symphony/symphony/issues/155

• materialize.go passs InstanceState, TargetState and SolutionState to API request body
• catalogprovider.go pass CatalogState to UpsertCatalog function
• remove duplicate UpsertTarget function in symphony-api.go (use CreateTarget instead)
• Rename SiteManager functions to GetState and ListState
• Update multisite scenario using catalog-catalog.yaml

Tests:

• Unit tests
• Multi-site manual test with catalog synchronization and remote jobs

I think we need to also fix this line, use catalog, not catalog.Spec in json.Marshal.
