Polaris Spark Catalog can't handle procedures

### Describe the bug

In most cases Polaris SparkCatalog acts as a wrapper around the iceberg catalog with added functionality. However Polaris catalog plugin currently doesn't handle procedures while iceberg implementation does. For v3.5 Iceberg uses it's own ProcedureCatalog, while for v4.0 the one in spark. It should be possible (?) to mimic iceberg behavior even in current 3.5 version by utilizing ProcedureCatalog interface from iceberg.

### To Reproduce

Call any of the procedures from [iceberg](https://iceberg.apache.org/docs/latest/spark-procedures/).

### Actual Behavior

Polaris SparkCatalog throws an error.

### Expected Behavior

Polaris SparkCatalog should delegate procedure calls to iceberg

### Additional context

_No response_

### System information

_No response_

Start at the Polaris SparkCatalog entry point and compare its procedure handling with the Iceberg Spark procedures described in the linked documentation. Check the version-specific ProcedureCatalog behavior for Spark 3.5, then verify that the listed Iceberg procedures are delegated without the current error.
