hvf: Add Apple Silicon support
With Apple Silicon available to the masses, it's a good time to add support
for driving its virtualization extensions from QEMU.
This patch adds all necessary architecture specific code to get basic VMs
working, including save/restore.
Known limitations:
- WFI handling is missing (follows in later patch)
- No watchpoint/breakpoint support
