Use a separate memory context for GIN scan keys.
It was getting tedious to track and release all the different things that
form a scan key. We were leaking at least the queryCategories array, and
possibly more, on a rescan. That was visible if a GIN index was used in a
nested loop join. This also protects from leaks in extractQuery method.
No backpatching, given the lack of complaints from the field. Maybe later,
after this has received more field testing.
