IMPALA-14484: Calcite planner: Add column stats to union slot descriptors
There is explicit code in SetOperationStmt which adds column stats to the
SlotDescriptor. This code is now reused to obtain the column stats for the
Calcite compiler and added to the union slot descriptors.
The tpcds unit tests now have better estimates.

> There are some tests in
> query_test.test_runtime_filters.TestRuntimeRowFilters.test_row_filters
> that are failing which have a union in them.
> The code can be traced to the fact that ColumnStats are added to union slot
> descriptors in the SetOperationStmt code. This code needs to be applied to
> the Calcite code.
