acrn-config: launch refinement on vcpu affinity and uos image

Browse Source 
1. The vcpus of UOS are configured in vm configuration, they should be offlined from
sos before vm start.
2. retry offline cpu for all UOS type.
3. uos image name will be based on vm name instead of input parameter.
4. correct the unexpected token ';;' in launch config.
