Support Snapshot Management Operations

### Feature Request / Improvement

Following is a list of operations that are supported in Spark:
- rollback_to_snapshot (set_ref_snapshot)
- rollback_to_timestamp (set_ref_snapshot)
- set_current_snapshot (set_ref_snapshot)
- cherrypick_snapshot
- publish_changes
- fast_forward

[set_ref_snapshot](https://github.com/apache/iceberg-python/pull/728) support will be introduced, but it would also be nice to add snapshot migration operations that generate new snapshots from existing ones

Start by reviewing the set_ref_snapshot work linked in the issue and the existing snapshot-management operations in PyIceberg. Compare the listed Spark operations with the project's current API and determine the intended behavior and tests for each migration operation. Done means the supported operations generate the expected snapshots and are covered by tests.
