HV: refine launch vm interface

Browse Source 
When pcpu enter guest mode, it will call launch_vms() function to launch
VMs in global vm_configs array.

In launch_vms() function, current pcpu will go through vm_config array list
and check whether it is a bsp of configured VM, if yes then it will prepare
corresponding VM and start it. The index of vm_config array will be specified
to VM id.

The first least significant bit in pcpu_bitmap means the bsp of the VM.

Tracked-On: #2291
