new ui create attribute definition screen

Make a screen in the new UI that is like the lite UI screen, but with the new UI look and feel and logic etc. Also make the screen easier to use:

• depending on the type of attribute, it can be assigned to certain owner types (e.g. permission can be assigned to roles or effective memberships). When selecting the type, auto hide/show the owner types that can be assigned

• depending on the value type, the attribute can be multi-assignable or not. If it is a marker, hide that field, if not, show it. If blank, then show.
