tools/libxl: allow setting of timer_mode, hpet and vpt_align parameters

Implement parsing for timer_mode, hpet and vpt_align parameters.

These are all HVM only parameters and hpet/vpt_align are boolean so
change types and place in hvm union accordingly. Also HPET is x86 only
on principle so make this compile-time conditional on arch as-is
viridian.
