This patch enables support for shared memory in guest_memfd, including mapping that memory at the host userspace. This support is gated by the configuration option KVM_GMEM_SHARED_MEM, and toggled by the guest_memfd flag GUEST_MEMFD_FLAG_SUPPORT_SHARED, which can be set when creating a guest_memfd instance.

Nit: I would split off the x86 bits. Meaning, this patch would only introduce the infrastructure and a x86 KVM patch would enable it for selected x86 VMs.
