Allow to assume role when connecting to AWS catalogs (glue/dynamodb)

### Feature Request / Improvement

At this moment, `role-arn` parameters (either with `client` or `s3` prefix) can be used to assume role before accessing S3 objects. I propose that this functionality is extended to catalog clients for AWS iceberg catalogs (glue/dynamodb). This will improve users experience, since other `client`-prefixed parameters are usually shared between s3 and glue/dynamodb.

Start by tracing the existing role-arn handling for S3 and the Glue/DynamoDB catalog clients. Confirm how shared client-prefixed parameters are passed to each catalog, then add coverage for assuming a role when connecting to both catalogs. Done means the role-arn options work for Glue and DynamoDB without regressing S3 behavior.
