vmm: Pass MemoryManager through CpuManager creation

Browse Source 
Instead of passing the GuestMemoryMmap directly to the CpuManager upon
its creation, it's better to pass a reference to the MemoryManager. This
way we will be able to know if SGX EPC region along with one or multiple
sections are present.
