afe6eb499d Revert "MDEV-20342 Turn Field::flags from a member to a method" 
This reverts commit e86010f909.

Reverting on Monty's request, as this change makes merging
things from 10.5 to 10.2 much harder.

MDEV-16620: Add JSON_ARRAYAGG function 
The JSON_ARRAYAGG function extends the GROUP_CONCAT function and provides
a method of aggregating JSON results. The current implementation supports
DISTINCT and LIMIT but not ORDER BY (Oracle supports GROUP BY).

Adding GROUP BY support is possible but it requires some extra work as the
grouping appears to be done inside a temporary table that complicates
matters.

Added test cases that covert aggregation of all JSON types and JSON
validation for the generated results.

979cad2291 MDEV-9531 GROUP_CONCAT with ORDER BY inside takes a lot of memory while it's executed 
group concat tree is allocated in a memroot, so the only way to free
memory is to copy a part of the tree into a new memroot.

track the accumilated length of the result, and when it crosses
the threshold  - copy the result into a new tree, free the old one.
