Fixing queries for Columnstore issue 459

[mprostko]

This PR adds the logic into MariaDB's OLAP benchmark scripts to use different queries based on the engine used. Resolves #459

The differences in table definition boil down to two things:

• column-store doesn't support column-level character set specification (eg, "binary")
• column-store doesn't support creation of PK/FKs

We could use variable replacement to deal with the charset difference, but there's no easy way to deal with the PK/FK differences, so duplicating the CREATE TABLE statements is the best solution at this point.

Have tested on a build of MariaDB 10.6 with th columnstore engine and the data is successfully loaded with this change. Note like all columnstores tested to date loading data through inserts is much (much!) slower than a row store and therefore bulk loading is recommended. Neverthless this change is very useful as it gives us the correct table structure to load into.
