Instead, use the new mechanism that allows planner extensions to store private state inside a PlannerInfo, treating GEQO as an in-core planner extension. This is a useful test of the new facility, and also buys back a few bytes of storage. To make this work, we must remove innerrel_is_unique_ext's hack of testing whether join_search_private is set as a proxy for whether the join search might be retried. Add a flag that extensions can use to explicitly signal their intentions instead.
