Introduce a generic kvm_mem_is_private() interface using a static call to
determine if a GFN is private. This allows the implementation for checking
a GFN's private/shared status to be set at runtime.

In preparation for choosing implementations between a guest_memfd lookup
and the existing VM attribute lookup, rename the existing
VM-attribute-based check to kvm_vm_mem_is_private to emphasize that it

Nit:
kvm_vm_mem_is_private -> kvm_vm_mem_is_private()

looks up VM attributes.
