Add views access plugins

This is not a feature request because grant only provide UI fragments and Views is the current recommended way to create a custom UI.

There are now the two views access plugins for role and for permission check which are cloned from core user module and connected to grant context strategy. To get this running I did some refactoring to get the access check through the same main class function from route access which is also used by views and the second check of views. The route access check can now be configured as multiple role check also from other contrib/custom modules. If using in contrib please do it like views is doing it a dynamical route change based on config because roles itself are config based.
