### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Manual test.
```scala
import org.apache.hive.service.rpc.thrift.TProtocolVersion
import org.apache.spark.sql.execution.HiveResult

val df = spark.sql("select id, cast(id as string), cast(id as timestamp) from range(200000)")
val dataTypes = df.schema.fields.map(_.dataType)
val rows = df.collect().toList
val start1 = System.currentTimeMillis()
RowSetUtils.toTRowSet(1, rows, dataTypes, TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V11, HiveResult.getTimeFormatters)
val start2 = System.currentTimeMillis()
RowSetUtils.toTRowSet(1, rows, dataTypes, TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V5, HiveResult.getTimeFormatters)
val start3 = System.currentTimeMillis()
println(s"toColumnBasedSet time: ${start2 - start1}, toRowBasedSet time: ${start3 - start2}")
```

Before this PR:
```
toColumnBasedSet time: 17307, toRowBasedSet time: 71
```

After this PR:
```
toColumnBasedSet time: 128, toRowBasedSet time: 70
```
