Max Gekk 35e6a9deee [SPARK-31353][SQL] Set a time zone in DateTimeBenchmark and DateTimeRebaseBenchmark 
### What changes were proposed in this pull request?
In the PR, I propose to set the `America/Los_Angeles` time zone in the date-time benchmarks `DateTimeBenchmark` and `DateTimeRebaseBenchmark` via `withDefaultTimeZone(LA)` and `withSQLConf(SQLConf.SESSION_LOCAL_TIMEZONE.key -> LA.getId)`.

The results of affected benchmarks was given on an Amazon EC2 instance w/ the configuration:
| 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 | OpenJDK8/11 |

### Why are the changes needed?
Performance of date-time functions can depend on the system JVM time zone or SQL config `spark.sql.session.timeZone`. The changes allow to avoid any fluctuations of benchmarks results related to time zones, and set a reliable baseline for future optimization.

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
By regenerating results of DateTimeBenchmark and DateTimeRebaseBenchmark.

Closes #28127 from MaxGekk/set-timezone-in-benchmarks.
