Description

Subtask of CALCITE-5549 to focus on the metadata we can control in calcite-core. Ensure that JDBC schema metadata and result set metadata agree on DATA_TYPE and TYPE_NAME for a MEASURE.

The challenging part will be writing tests for this. CalciteRemoteDriverTest.java has some that might be useful but use class Employee for a schema. We'll need a way to set some test MEASURE types as well.
