acrn-dm: implement cpu_affinity command line argument

Browse Source 
User has a chance to specify VCPU affinity through acrn-dm command line
argument. Examples of the command line:

3 PCPUs: 1/2/3
--cpu_affinity 1-3

5 PCPUs: 2/3/6/7/8
--cpu_affinity 2,3,6-8

8 PCPUs: 2/3/6/7/9/10/11/12
--cpu_affinity 2,3,6-7,9,10-12

The specified pCPUs must be included in the guest VM's statically
defined vm_config[].cpu_affinity_bitmap.
