Add support for the coreCount property in DBus

This commit introduces support for counting the number of CPU cores
during BMC power-on and populates this information to a DBus property
named coreCount. Upon BMC power-on, the remote terminus detects the
number of CPU cores and send this data and PLDM will updates the
coreCount property accordingly.

Tested:
tested on simulator for hosting DBus property
