feat: add model serving resource classes

[threcc]

Summary

Add auto-generated resource classes for RHOAI model serving component, generated from a cluster running RHOAI 3.5 GA.

New resources

• HTTPRoute (gateway.networking.k8s.io)
• InferencePool (inference.networking.k8s.io + inference.networking.x-k8s.io)
• Kuadrant (kuadrant.io)
• LocalModelNamespaceCache (serving.kserve.io)

Updated resources

• LLMInferenceService — regenerated from 3.5 CRD, adds kv_cache_offloading, scaling, storage_initializer, tracing, spec_annotations, spec_labels
• LLMInferenceServiceConfig — regenerated from 3.5 CRD, same new fields as above

Other changes

• Added INFERENCE_NETWORKING_K8S_IO and INFERENCE_NETWORKING_X_K8S_IO API group constants to Resource.ApiGroup
• Updated schema archive
• Added test manifests and test entries for all new/updated resources

Supersedes #2744.

Ref: RHOAIENG-71449

Walkthrough

Adds six generated Kubernetes resource kinds, inference networking API-group constants, specification serialization, required-field validation, and generator test coverage. It also extends LLMInferenceService with six optional specification fields.
