acrn-config: rename MAX_PLATFORM_CLOS_NUM to HV_SUPPORTED_MAX_CLOS

Browse Source 
HV_SUPPORTED_MAX_CLOS:
 This value represents the maximum CLOS that is allowed by ACRN hypervisor.
 This value is set to be least common Max CLOS (CPUID.(EAX=0x10,ECX=ResID):EDX[15:0])
 among all supported RDT resources in the platform. In other words, it is
 min(maximum CLOS of L2, L3 and MBA). This is done in order to have consistent
 CLOS allocations between all the RDT resources.
