[CARBONDATA-2649] Fixed arrayIndexOutOfBoundException while loading Blocklet DataMap after alter add column operation

Things done as part of this PR

Fixed arrayIndexOutOfBoundException while loading Blocklet DataMap after alter add column operation
Problem:
Array Index out of bound exception was thrown after alter add column operation.

Analysis:
After alter add column operation if COLUMN_META_CACHE is set on the newly added columns, then on executing select query on the data loaded before alter operation threw exception. This was because minMaxCache caching columns were fetched irrespective of the segmentProperties. Data loaded before alter add column operation will not have the newly added columns in its columnSchemaList and hence can throw exception if non existent column are not removed from min/max column cache. Solution:
Fetch the min/max cache columns based on segmentProperties

This closes #2510
