drivers/timer: Add default z_clock_set_timeout() fallback

Browse source 
Useful for tick-only drivers like Pulpino that don't support this.
Ideally we'd have a header-level interface definition for individual
timer drivers to eliminate the noop function call, but this is clean
for now (even the Pulpino hardware looks like it should support
timeouts just fine, so effort would be better spent there than on a
clean "ticked" interface).
