 bsps/x86_64: Add APIC timer based clock driver

 The APIC timer is calibrated by running the i8254 PIT for a fraction of a
 second (determined by PIT_CALIBRATE_DIVIDER) and counting how many times
 APIC counter has ticked. The calibration can be run multiple times
 by APIC_TIMER_NUM_CALIBRATIONS) and averaged out.

 Updates #2898.
