Closes #7709
Rationale for this change
While reviewing #7708 from @sarutak I spent time looking into what
plan_qdoes and it is not at all clear to me it needs to be built in release mode:https://github.com/apache/arrow-datafusion/blob/46cdb8c2dc495e8063a0adc5c3f9ac82b136e72e/benchmarks/src/tpch/run.rs#L297-L453
Since the benchmark verifies the plans (rather than actually running them). I think it is ok to use debug mode (rather than release) mode which compiles faster and will have more reuse with the subsequent call to
