[CARBONDATA-3515] Limit local dictionary size to 16MB and allow configuration.

problem: currently local dictionary max size is 2GB, because of this, for varchar columns or long string columns,
local dictionary can be of 2GB size. so, as local dictionary is stored in blocklet. blocklet size will exceed 2 GB,
 even though configured maximum blocklet size is 64MB. some places inter overflow happens during casting.

solution: Limit local dictionary size to 16MB and allow configuration. default size is 4MB

This closes #3380
