[PATCH v14 02/21] KVM: Rename CONFIG_KVM_GENERIC_PRIVATE_MEM to CONFIG_KVM_GENERIC_GMEM_POPULATE

[Fuad Tabba <tabba@google.com>]

The original name was vague regarding its functionality. This Kconfig
option specifically enables and gates the kvm_gmem_populate() function,
which is responsible for populating a GPA range with guest data.

The new name, KVM_GENERIC_GMEM_POPULATE, describes the purpose of the
option: to enable generic guest_memfd population mechanisms. This
improves clarity for developers and ensures the name accurately reflects
the functionality it controls, especially as guest_memfd support expands
beyond purely "private" memory scenarios.
