Fixes #18015. ### Description Fixes an issue where attempting to load iceberg tables from an AWS Glue catalog fails with ClassNotFound exceptions. AWS Glue catalog internally uses [DynConstructors](https://iceberg.apache.org/javadoc/1.6.1/org/apache/iceberg/common/DynConstructors.html) which uses reflection to locate certain Glue-related classes from the iceberg-aws dependency. This uses the [current thread context classloader](https://github.com/apache/iceberg/blob/apache-iceberg-1.6.1/common/src/main/java/org/apache/iceberg/common/DynConstructors.java#L119) to locate it but these classes are only available on the application classloader. This PR does a context classloader switch to fix the issue. #### Release note Fixes an issue where loading Iceberg tables from the AWS Glue Catalog could fail due to ClassNotFoundException exceptions. <hr> <!-- Check the items by putting "x" in the brackets for the done things.
