Introduce info.magnolia.ui.editor.MultiFormView.EntryResolution extender, that will resolve multi items as properties.

Why MultiValueAsMultipleProperties cannot be used

MultiValueAsMultipleProperties ItemProvider was thought that it could simulate similar behavior. I checked, it doesn't. What is necessary to achieve properties persisted under a multi-field is a different EntryResolution mechanism. Using current EntryResolution mechanisms with MultiValueAsMultipleProperties does not help, since MultiValueAsMultipleProperties is a CurrentItemProvider extension, thus, items are resolved to root and are not stored within a multi-field root, as is necessary for MultiValueAsMultipleProperties
