KVM: VMX: Add a macro to track which DEBUGCTL bits are host-owned

Browse source

Add VMX_HOST_OWNED_DEBUGCTL_BITS to track which bits are host-owned, i.e.
need to be preserved when running the guest, to dedup the logic without
having to incur a memory load to get at kvm_x86_ops.HOST_OWNED_DEBUGCTL.

No functional change intended.
