DRILL-7414: EVF incorrectly sets buffer writer index after rollover

Enabling the vector validator on the "new" scan operator, in cases
in which overflow occurs, identified that the DrillBuf writer index
was not properly set for repeated vectors.

Enables such checking, adds unit tests, and fixes the writer index
issue.
