Test: Add unit tests for order-independent binding comparison

Add comprehensive unit tests to validate the new set-based binding
comparison logic in iis_site type. Tests verify that:

- Bindings with identical content but different order are in sync
- Bindings with different content are correctly detected as out of sync
- Bindings with different counts are properly identified as out of sync

These tests ensure the order-independent comparison works correctly
and prevent regression to order-sensitive behavior.
