[SPARK-45470][SQL] Avoid paste string value of hive orc compression kind
### What changes were proposed in this pull request?
Currently, Hive supports ORC format with some compression codec( Please
refer
[ql/src/java/org/apache/hadoop/hive/ql/io/orc/CompressionKind.java](https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/io/orc/CompressionKind.java)).
Spark pasted many string literal of these compression codec. It is easy to
make mistakes and reduce development efficiency.
### Why are the changes needed?
Avoid paste string value of hive orc compression kind
### Does this PR introduce _any_ user-facing change?
'No'.
Just update inner implementation.
### How was this patch tested?
Exists test cases.
### Was this patch authored or co-authored using generative AI tooling?
'No'.
Closes #43296 from beliefer/SPARK-45470.
