Support ORC File Reading with Writer's Time Zone

Support ORC file read by writer's time zone. #66025 (kevinyhzou).
Support reading ORC files by applying the writer's time zone to correctly interpret timestamp data.

Why it matters

This feature addresses the issue of incorrect timestamp interpretation when reading ORC files by using the time zone information embedded by the file writer. It ensures that timestamp data is accurately converted and consistent with the original data time zone, improving data correctness and reliability for users working with ORC files.

How to use it

When reading ORC files, ClickHouse will automatically apply the writer's time zone to timestamp columns. Users do not need to configure anything explicitly to enable this behavior; it is handled internally during ORC file reading operations.
