KVM: guest_memfd: Rename prepare() hook and Kconfig to make_private() / CONVERT

Rework guest_memfd's prepare() hook into a more accurate make_private(), and rework its Kconfig from PREPARE to a more generic CONVERT. This will allow x86 to share (pun intended) a kvm_x86_ops.gmem_make_shared() hook between the "convert to shared" and "reclaim" flows, which are one and the same for SNP. No functional change intended.
