KVM: x86: Move nested_ops out of kvm_x86_ops, to global kvm_nested_ops

Rework KVM's handling of per-vendor nested ops to copy the vendor's ops
into a global structure owned by common x86, i.e. treat nested ops just
like x86 and PMU ops.  In addition to providing consistency across all ops
implementations, making a copy of the ops prevents changes to the vendor's
ops after KVM is initialized, i.e. guards against goofs where KVM *thinks*
it is updating nested ops, but which won't take effect now that KVM uses
static calls to invoke vendor hooks.

Ignoring the side effects of tagging {svm,vmx}_nested_ops as __initdata,
no functional change intended.
