Filters out activity items the user is not allowed to see.

The access to the activity items may be limited by the following: 1. Value in field_visibility_value on a Post entity. 2. Node access grants (this includes the field_node_visibility_value and the nodes in a closed group) 3. The comment or post is posted in a (closed) group.

In addition to the condition used in this filter there may be some other filters active in the given view (e.g. destination).

Probably want to extend this to entity access based on the node grant system when this is implemented. See https://www.drupal.org/node/777578
