HV: make vm id statically by uuid

Browse Source 
Currently VM id of NORMAL_VM is allocated dymatically, we need to make
VM id statically for FuSa compliance.

This patch will pre-configure UUID for all VMs, then NORMAL_VM could
get its VM id/configuration from vm_configs array by indexing the UUID.

If UUID collisions is found in vm configs array, HV will refuse to
load the VM;

Tracked-On: #2291
