KVM: SVM: Move core EFER.SVME enablement to kernel

Browse source

Move the innermost EFER.SVME logic out of KVM and into to core x86 to land
the SVM support alongside VMX support.  This will allow providing a more
unified API from the kernel to KVM, and will allow moving the bulk of the
emergency disabling insanity out of KVM without having a weird split
between kernel and KVM for SVM vs. VMX.

No functional change intended.
