KVM: SVM: Add VMLOAD and VMSAVE handlers

This implements the VMLOAD and VMSAVE instructions, that usually surround
the VMRUN instructions. Both instructions load / restore the same elements,
so we only need to implement them once.

v2 fixes CPL checking and replaces memcpy by assignments
v3 makes use of the new permission checking
