HIVE-29413: Avoid code duplication by updating getPartCols method for iceberg tables

[ramitg254]

What changes were proposed in this pull request?

updated getPartCols method and introduced a boolean parameter in it to handle partition keys needed for non native tables and to get rid of this kind of code redundancy in some places:

table.hasNonNativePartitionSupport() ?
            table.getStorageHandler().getPartitionKeys(table) :
            table.getPartCols();

Why are the changes needed?

to avoid code redundancy and have a common method to retrieve keys for both native and non native tables.

Does this PR introduce any user-facing change?

No
