 Description   

cpimport, when loading wide decimals creates corrupted data which will cause incorrect extent elimination.

The root cause is the failure of cpimport to properly communicate with DBRM.

The code change for cpimport is accompanied by test scripts to verify the feature (see Pull Request)

Relevant branch: https://github.com/mariadb-SergeyZefirov/mariadb-columnstore-engine/tree/MCOL-4652-Support-for-wide-decimals-in-cpimport-communication-with-DBRM

Contains test and code changes needed for test to pass.

May be useful for performance tests on wide decimal columns joins.

I did not miss the fact that PR #1956 was merged on June 1st. PR #1840 was declined a day later. Confirmed with drrtuythat PR #1840 will be ignored and the ticket is ready for testing.
