Max Gekk bef5828e12 [SPARK-31630][SQL] Fix perf regression by skipping timestamps rebasing after some threshold 
### What changes were proposed in this pull request?
Skip timestamps rebasing after a global threshold when there is no difference between Julian and Gregorian calendars. This allows to avoid checking hash maps of switch points, and fixes perf regressions in `toJavaTimestamp()` and `fromJavaTimestamp()`.

### Why are the changes needed?
The changes fix perf regressions of conversions to/from external type `java.sql.Timestamp`.

Before (see the PR's results https://github.com/apache/spark/pull/28440):

```

Perf improvements in average of:

1. From java.sql.Timestamp is ~ 34%
2. To java.sql.Timestamps is ~16%

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

### How was this patch tested?
By existing test suites `DateTimeUtilsSuite` and `RebaseDateTimeSuite`.

Closes #28441 from MaxGekk/opt-rebase-common-threshold.
