Optionally filter views results by the states a user has permissions for.

Problem/Motivation

Content Moderation disallows edit access to entities based on whether a user can use any transitions for the entities current state. It would be nice to be able to replicate that in views, so that a view can display only those entities that a user can edit.

Proposed resolution

1: Set a setting in the settings form.
2: If that setting is true, then filter the states before the query condition is created.
