Add vSphere platform=none Windows Containers CI jobs

Add vSphere platform=none Windows Containers CI jobs for OCP 4.18-4.22

Summary

This PR adds periodic and debug presubmit CI jobs for Windows Containers testing on vSphere platform=none (UPI) for OpenShift versions 4.18 through 4.22.

This is to test platform=none seamlessly and validate that Windows Container tests work correctly on UPI clusters without Machine API.

Changes

CI Job Configurations

Release 4.18-4.21:

• Added debug presubmit jobs (debug-winc-vsphere-none)
• Triggered on changes to test/extended/winc/ directory
• Uses cucushift-installer-rehearse-vsphere-none-ovn-winc workflow

Release 4.22 (active release):

• Added periodic job (vsphere-none-ovn-winc-f7) - runs weekly
• Added debug presubmit job - triggered by code changes
• Provides comprehensive coverage for the current development release

New Workflow

Created cucushift-installer-rehearse-vsphere-none-ovn-winc workflow:

• Provisions vSphere UPI cluster with platform: none and OVN hybrid overlay networking
• Uses existing upi-vsphere-platform-none-ovn-pre chain for cluster provisioning
• Provisions Windows VMs via upi-vsphere-windows-pre (vSphere VM provisioning)
• Deploys WMCO (Windows Machine Config Operator) from Konflux
• Uses cucushift-installer-check-upi chain to skip controlplanemachinesets validation

Shared Step Registry Components (from AWS PR)

1. UPI Check Chain
ci-operator/step-registry/cucushift/installer/check/upi/

Installer health check chain for UPI clusters that excludes controlplanemachinesets validation:

• Platform=none clusters don't support ControlPlaneMachineSets
• Includes all other checks (operators, info, capability, realtime, compact, fips)

2. BYOH Windows Workload Preparation
ci-operator/step-registry/cucushift/winc/prepare/byoh/

Prepares Windows Container test workloads for BYOH/UPI clusters:

• Sets up ImageTagMirrorSet to redirect Windows images to CI registry mirror
• Waits for Windows nodes to become Ready and schedulable
• Removes CCM uninitialized taint from Windows nodes (BYOH nodes don't need CCM)
• Creates test workloads (Windows and Linux deployments, services)
• Validates workloads are running before tests begin

Technical Details

vSphere Platform=None Architecture

Platform=none on vSphere:

• No cloud provider integration
• No Machine API / no MachineSets
• Manual VM provisioning via vSphere
• OVN hybrid overlay for Windows networking
• No CCM (Cloud Controller Manager) taints

OVN Hybrid Networking

Windows Containers require OVN hybrid overlay networking:

• Linux nodes: Standard OVN-Kubernetes
• Windows nodes: Hybrid overlay network
• Configuration via Network CR manifests
• Created by ovn-conf-hybrid-manifest-with-custom-vxlan-port step
