Set Calendar type used for temporal types in ORC footer

[marcinsbd]

Description

The aim of this change is to add to the ORC file's footer the calendar type that was used to represent the dates or timestamps. Trino uses the Proleptic Gregorian calendar. The motivation behind is compatibility of that ORC files written by Trino to be properly readable by other tools like Apache Hive that can read ORC files.

Pull Request Overview

This PR adds support for setting the calendar type in ORC file footers for temporal data types. When writing ORC files, the system now detects if temporal types (DATE, TIMESTAMP, TIMESTAMP_INSTANT) are present and sets the appropriate calendar metadata in the footer.

Key changes:

• Added CalendarKind enum with three calendar types: UNKNOWN_CALENDAR, JULIAN_GREGORIAN, and PROLEPTIC_GREGORIAN
• Enhanced Footer class to include optional calendar metadata
• Implemented logic to automatically set PROLEPTIC_GREGORIAN calendar when temporal types are detected during ORC writing

Everything looks good. The only point left is the decision around reading, which I expect should not significantly impact the PR’s structure
