minor: Refactor expression microbenchmarks to remove duplicate code

[andygrove]

Which issue does this PR close?

Part of #2955

Rationale for this change

Each expression microbenchmark repeats the following code, but with differences in naming:

        benchmark.addCase("SQL Parquet - Spark") { _ =>


          spark.sql(query).noop()
        }

        benchmark.addCase("SQL Parquet - Comet (Scan)") { _ =>
          withSQLConf(CometConf.COMET_ENABLED.key -> "true") {
            spark.sql(query).noop()
          }
        }

        benchmark.addCase("SQL Parquet - Comet (Scan, Exec)") { _ =>
          withSQLConf(
            CometConf.COMET_ENABLED.key -> "true",
            CometConf.COMET_EXEC_ENABLED.key -> "true") {
            spark.sql(query).noop()
          }
        }

This PR moves this logic into a base class and re-uses it across all existing expression microbenchmarks.

Minor : Would we be needing exec and scan exec for all types of benchmarks @andygrove ?

[andygrove]

Yes, I only updated expression benchmarks in this PR but will follow up for the other ones (shuffle, exec, aggregate) in separate PRs in the future but those ones are a little more involved. My short term goal is to add benchmarks for all expressions, so wanted to refactor the expression benchmarks before doing that.

Might want to fix unused imports to pass CI
