Kernel: Expose timers via a TimerId type

Browse source 
The public consumers of the timer API shouldn't need to know
the how timer id's are tracked internally. Expose a typedef
instead to allow the internal implementation to be protected
from potential churn in the future.

It's also just good API design.
