[SPARK-31398][SQL] Fix perf regression of loading dates before 1582 year by non-vectorized ORC reader
### What changes were proposed in this pull request? In regular ORC reader when `spark.sql.orc.enableVectorizedReader` is set to `false`, I propose to use `DaysWritable` in reading DATE values from ORC files. Currently, days from ORC files are converted to java.sql.Date, and then to days in Proleptic Gregorian calendar. So, the conversion to Java type can be eliminated. ### Why are the changes needed? - The PR fixes regressions in loading dates before the 1582 year from ORC files by when vectorised ORC reader is off. - The changes improve performance of regular ORC reader for DATE columns. - x3.6 faster comparing to the current master - x1.9-x4.3 faster against Spark 2.4.6 Before (on JDK 8): ``` Load dates from ORC: Best Time(ms) Avg Time(ms) Stdev(ms) Rate(M/s) Per Row(ns) Relative ------------------------------------------------------------------------------------------------------------------------ after 1582, vec off 39651 39686 31 2.5 396.5 1.0X after 1582, vec on 3647 3660 13 27.4 36.5 10.9X before 1582, vec off 38155 38219 61 2.6 381.6 1.0X before 1582, vec on 4041 4046 6 24.7 40.4 9.8X ``` After (on JDK 8): ``` Load dates from ORC: Best Time(ms) Avg Time(ms) Stdev(ms) Rate(M/s) Per Row(ns) Relative ------------------------------------------------------------------------------------------------------------------------ after 1582, vec off 10947 10971 28 9.1 109.5 1.0X after 1582, vec on 3677 3702 36 27.2 36.8 3.0X before 1582, vec off 11456 11472 21 8.7 114.6 1.0X before 1582, vec on 4079 4103 21 24.5 40.8 2.7X ``` Spark 2.4.6: ``` Load dates from ORC: Best Time(ms) Avg Time(ms) Stdev(ms) Rate(M/s) Per Row(ns) Relative ------------------------------------------------------------------------------------------------------------------------ after 1582, vec off 48169 48276 96 2.1 481.7 1.0X after 1582, vec on 5375 5410 41 18.6 53.7 9.0X before 1582, vec off 22353 22482 198 4.5 223.5 2.2X before 1582, vec on 5474 5475 1 18.3 54.7 8.8X ``` ### Does this PR introduce any user-facing change?
