[SPARK-26720][SQL] Remove DateTimeUtils methods based on system default
time zone
## What changes were proposed in this pull request?
In the PR, I propose to remove the following methods from `DateTimeUtils`:
- `timestampAddInterval` and `stringToTimestamp` - used only in test suites
- `truncTimestamp`, `getSeconds`, `getMinutes`, `getHours` - those methods
assume system default time zone. They are not used in Spark.
## How was this patch tested?
This was tested by `DateTimeUtilsSuite` and `UnsafeArraySuite`.
Closes #23643 from MaxGekk/unused-date-time-utils.
