hvf: arm: Implement -cpu host

Browse source 
Now that we have working system register sync, we push more target CPU
properties into the virtual machine. That might be useful in some
situations, but is not the typical case that users want.

So let's add a -cpu host option that allows them to explicitly pass all
CPU capabilities of their host CPU into the guest.
