[Maria-developers] MDEV-11514, MDEV-11497, MDEV-11554, MDEV-11555 - IN and CASE type aggregation problems

Hello Sanja, Please review a patch fixing a number of problems in IN and CASE. This is a per-requisite for further Type_handler related work, to clean-up the code before moving it to more IN and CASE related methods in Type_handler. Thanks!
