Add ExplainState argument to pg_plan_query() and planner().
This allows extensions to have access to any data they've stored
in the ExplainState during planning. Unfortunately, it won't help
with EXPLAIN EXECUTE is used, but since that case is less common,
this still seems like an improvement.
Since planner() has quite a few arguments now, also add some
documentation of those arguments and the return value.
