hvf: arm: Implement -cpu host 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.

hvf: add guest debugging handlers for Apple Silicon hosts Guests can now be debugged through the gdbstub. Support is added for single-stepping, software breakpoints, hardware breakpoints and watchpoints. The code has been structured like the KVM counterpart. While guest debugging is enabled, the guest can still read and write the DBG*_EL1 registers but they don't have any effect.
