class ViewUIConverter in Zircon Profile 8

Provides upcasting for a view entity to be used in the Views UI.

Example:

pattern: '/some/{view}/and/{bar}' options: parameters: view: type: 'entity:view' tempstore: TRUE

The value for {view} will be converted to a view entity prepared for the Views UI and loaded from the views temp store, but it will not touch the value for {bar}.
