darwin-aarch64: hvf: run a cpu

Bug: 173766929

Remove the stub, at least. This adds a very skeleton level of support
for Hypervisor.framework on Apple Silicon, allowing us to run one slice
of vcpu (can set up registers as specified by hw/arm firmware, and run
until the first exit).

TODO

- This runs a vcpu but it gets stuck on older kernels. Makes progress
(exception) when running a 5.4 mainline kernel.
- Add interrupts/events
- Add enough insn emulator to service MMIO
