Fix km_ebpfcore_restart_test to run inside VM

[Alan-Jowett]

Problem

The km_ebpfcore_restart_test has been failing every scheduled run since it was introduced (issue #4950). The previous RCA (Chocolatey missing) was fixed by PR #4968, but the test continues to fail with a new error:

Failed to create map, error: -1 Failed to open ebpfcore service, error: 1060 FAIL: ebpfcore service does not exist - environment issue!

Root Cause

The test command .\ebpf_restart_test_controller.exe was invoked directly on the 1ES runner host, but the eBPF components (ebpfcore service) are installed inside the Hyper-V VM (runner_vm) by setup_ebpf_cicd_tests.ps1. Error 1060 is ERROR_SERVICE_DOES_NOT_EXIST.

Other KM tests (e.g., km_mt_stress_tests_restart_extension) correctly route execution through execute_ebpf_cicd_tests.ps1, which uses Invoke-OnHostOrVM to run inside the VM.

Fix

Route the restart test through the existing VM execution infrastructure:

1. cicd.yml - Changed test_command to use execute_ebpf_cicd_tests.ps1 with RestartEbpfCore option
2. run_driver_tests.psm1 - Added RestartEbpfCore parameter to Invoke-CICDStressTests
3. vm_run_tests.psm1 - Passes the new option through

Fixes #4950

Pull request overview

This PR fixes the km_ebpfcore_restart_test CI job by routing execution through the existing VM-based test execution path, ensuring the restart controller runs inside the Hyper-V VM where ebpfcore is installed.

Changes:

• Update the km_ebpfcore_restart_test workflow command to call execute_ebpf_cicd_tests.ps1 with a new stress-test option (RestartEbpfCore).
• Add a RestartEbpfCore switch to Invoke-CICDStressTests to run ebpf_restart_test_controller.exe via the standard VM test harness.
• Plumb the new option through vm_run_tests.psm1 option parsing and into Invoke-CICDStressTests.

File	Description
.github/workflows/cicd.yml	Runs the restart test through execute_ebpf_cicd_tests.ps1 so it executes inside the VM.
scripts/vm_run_tests.psm1	Recognizes RestartEbpfCore in -Options and forwards it to stress test invocation.
scripts/run_driver_tests.psm1	Implements RestartEbpfCore handling in Invoke-CICDStressTests to execute the restart controller.
