MDEV-31411: JSON_ARRAY_INTERSECT/JSON_OBJECT_FILTER_KEYS should fetch

Browse Source 
data from a table similar to other JSON functions

Analysis:
Since we are fetching values for every row ( because we are running SELECT
for all rows of a table ), correct value can be only obtained at the time of
calling val_int() because it is called to get value for each row.
Fix:
Set up hash for each row instead of doing it during fixing fields.
