sys_clock.h: Make "global variable" APIs into proper functions

Browse source 
The existing API defined sys_clock_{hw_cycles,ticks}_per_sec as simple
"variables" to be shared, except that they were only real storage in
certain modes (the HPET driver, basically) and everywhere else they
were a build constant.

Properly, these should be an API defined by the timer driver (who
controls those rates) and consumed by the clock subsystem.  So give
them function syntax as a stepping stone to get there.

Note that this also removes the deprecated variable
_sys_clock_us_per_tick rather than give it the same treatment.
