### What changes were proposed in this pull request? Add benchmarks for interval constructor `make_interval` and measure perf of 4 cases: 1. Constant (year, month) 2. Constant (week, day) 3. Constant (hour, minute, second, second fraction) 4. All fields are NOT constant. The benchmark results are generated in the environment: | Item | Description | | ---- | ----| | Region | us-west-2 (Oregon) | | Instance | r3.xlarge | | AMI | ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20190722.1 (ami-06f2f779464715dc5) | | Java | OpenJDK 64-Bit Server VM 1.8.0_252 and OpenJDK 64-Bit Server VM 11.0.7+10 | ### Why are the changes needed? To have a base line for future perf improvements of `make_interval`, and to prevent perf regressions in the future. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? By running `IntervalBenchmark` via: ``` $ SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.IntervalBenchmark" ``` Closes #28905 from MaxGekk/benchmark-make_interval.
