chore: generate code for new Apigee resources

Generate all required code artifacts for the 19 new Apigee resources:

Generated artifacts:
- API type definitions for cluster and namespaced scopes (v1beta1)
- Terraform resource bindings and state management
- CustomResourceDefinitions (CRDs) for Kubernetes integration
- Example YAML manifests demonstrating resource usage
- Controller setup and registration code

This includes:
- 76+ type definition files (apis/cluster/apigee/v1beta1/ and apis/namespaced/apigee/v1beta1/)
- 38 CRD manifests (package/crds/apigee.gcp.*.io_*.yaml)
- 66 example YAML files (examples-generated/{cluster,namespaced}/apigee/v1beta1/)
- 38 controller directories with generated reconciliation logic
- Updated controller setup files for resource registration

All generated code follows the upjet code generation patterns and
includes proper reference resolution, deep copy methods, and conversion
hubs for API version management.
