/events: Move `WithClock` to `unit` build tagged file

[JoshVanL]

Reverts https://github.com/dapr/kit/pull/62

WithClock should be moved to unit build tagged files to not pollute implementation non-test builds. Developers wanting to override the clock in testing can do so by go testing with the unit build tag.

#62 was made on purpose. Please don’t reverse this.

I don't see the technical reason for needing WithClock in the implementation code. The mock code is still available in tests with the unit build tag.
