feat: merge wing328's anyOf test samples and regenerate with true anyOf support

- Merged PR OpenAPITools#21911 from wing328 which adds anyOf test samples
- Regenerated samples with our new anyOf implementation
- Models now correctly generate as structs with optional fields (OR semantics)
- ModelIdentifier and AnotherAnyOfTest demonstrate proper anyOf behavior
