Title: [JENKINS-20739] Filter descriptors before adding them to hetero-list.

This allows implementations of {{DescriptorVisibilityFilter}} to hide items
with descriptors from users to prevent them from being added via the UI
using hetero lists.

This is already implemented in {{/lib/hudson/newFromList/form.jelly}}, but
nowhere else.
