## What changes were proposed in this pull request? In the PR, I propose to avoid the `TimeZone` to `ZoneId` conversion in `DateTimeUtils.stringToTimestamp` by changing signature of the method, and require a parameter of `ZoneId` type. This will allow to avoid unnecessary conversion (`TimeZone` -> `String` -> `ZoneId`) per each row. Also the PR avoids creation of `ZoneId` instances from `ZoneOffset` because `ZoneOffset` is a sub-class, and the conversion is unnecessary too. ## How was this patch tested? It was tested by `DateTimeUtilsSuite` and `CastSuite`. Closes #24155 from MaxGekk/stringtotimestamp-zoneid.
