clock: remove z_ from semi-public APIs

Browse source 
The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers
and add support for new hardware and are documented and available to be
used outside of the clock/kernel subsystems.

Remove the leading z_ and provide them as clock_* APIs for someone
writing a new timer driver to use.
