timekeeping: Add missing _ns functions for coarse accessors
This further unifies the accessors for the fast and coarse functions, so
that the same types of functions are available for each. There was also
a bit of confusion with the documentation, which prior advertised a
function that has never existed. Finally, the vanilla ktime_get_coarse()
was omitted from the API originally, so this fills this oversight.
