refactor(iceberg): Remove unnecessary column type translation method

[hantangwangd]

Description

In PR #21662, we have merged IcebergColumnHandle.ColumnType and HiveColumnHandle.ColumnType into a single enum class and extracted it into their common parent class BaseHiveColumnHandle. As a result, the method previously used for converting between these two types, along with its invocations, are no longer necessary. This PR remove the unnecessary method getHiveColumnHandleColumnType and its invocations.
