KVM: x86/mmu: split cpu_role from mmu_role
Snapshot the state of the processor registers that govern page walk into
a new field of struct kvm_mmu. This is a more natural representation
than having it *mostly* in mmu_role but not exclusively; the delta
right now is represented in other fields, such as root_level.
The nested MMU now has only the CPU role; and in fact the new function
kvm_calc_cpu_role is analogous to the previous kvm_calc_nested_mmu_role,
except that it has role.base.direct equal to !CR0.PG. For a walk-only
MMU, "direct" has no meaning, but we set it to !CR0.PG so that
role.ext.cr0_pg can go away in a future patch.
