Adding CPUCore interface support
This commit introduces essential D-Bus infrastructure support for
hosting the `Item.CPUCore` D-Bus object. Additionally, it includes
getter and setter functions to enable get/set properties within the
`CPUCore` interface, such as core count and microcode.
Testing:
Unit test passed
