Improve case for lifecycle interface to create guest XML by the framework

[yiqianwei]

1.Add some parameters to allow the framework provide guest xml
2.Add "only Linux" to limit guest type
3.Skip the OVS bridge test

ID: 22423

Summary by CodeRabbit

• Tests
  • Enhanced virtual network lifecycle test configuration: restricted to Linux, improved VM provisioning and teardown, switched to no-reboot mode, and added an OVMF-specific override affecting VM teardown behavior (uses NVRAM option).
  • Added an earlier validation to cancel/skip tests for OVS-bridge scenarios before VM setup.

Walkthrough

The PR updates a virtual network test configuration to restrict execution to Linux, enable libvirt VM creation and teardown, set no-reboot mode, and add an OVMF-specific libvirt kill option (--nvram). The test runner now invokes an OVS-bridge cancellation check at the start of run() (before determining the main VM and backing up VM XML), introducing an earlier conditional skip point prior to the existing setup/start/check/teardown lifecycle.
