kernel64 - Add some lapic timer based debugging (disabled by default)

* Adjust the Xtimer interrupt to unconditionally call
  lapic_timer_always() regardless of the critical section state.

* Create a procedure lapic_timer_always() on x86-64 which is #if 0'd
  out by default with some on-screen debugging that can be used to
  help find system lockups.
