HPSTRAT-202: enhancement: ControlPlaneUpgradeable condition for HyperShift

[apahim]

Summary

• Adds a new enhancement proposing a ControlPlaneUpgradeable status condition on HostedControlPlane and HostedCluster
• Separates control-plane and data-plane upgrade readiness signals so that data-plane operators and user-installed OLM operators can no longer block control plane y-stream upgrades
• The HCCO aggregates Upgradeable from a known set of CP-side ClusterOperators; isUpgrading prefers this over ClusterVersionUpgradeable when available
• Gated behind ControlPlaneUpgradeableCondition feature gate (DevPreview → TechPreview → GA)
