vmm(4), bhyve(8): Expose kernel-emulated special devices to userspace

Expose the special kernel LAPIC, IOAPIC, and HPET devices to userspace
for use in, e.g., fallback instruction emulation (when userspace has a
newer instruction decode/emulation layer than the kernel vmm(4)).

Plumb the ioctl through libvmmapi and register the memory ranges in
bhyve(8).
