Add KVM gmem support to RAMBlock so both normal hva based memory
and kvm gmem fd based private memory can be associated in one RAMBlock.

Introduce new flag RAM_KVM_GMEM. It calls KVM ioctl to create private
gmem for the RAMBlock when it's set.


But who sets RAM_KVM_GMEM and when? Don't we simply allocate it for all RAMBlocks under such special VMs? What's the downside of doing that?
