  1. MDEV-26182: Implement JSON_INTERSECT() 

    The behavior of intersection of different types is different. Taking the
intersection of two objects is taking their common KV pairs. The intersection
of array and array is to take their common elements. There is no intersection
between scalar and object. An object and a scalar take an intersection with an
array. As long as the object or scalar exists in the array, the intersection
is the object or the scalar.

We put a json into the hash, scan another json, and efficiently get the
intersection by reading and updating the hash information.
