I have pulled this commit out of my ongoing work to add timers to `DoFn`,
specifically my branch where I add `DoFnInvoker.invokeOnTimer(<id>, ...)`.
For users, timers will have IDs. This is a step towards that API. I think
it is also just better in most ways, especially for being able to delete timers
without having to know exactly when it was set for.
Before this change, a timer's ID is its `TimeDomain` + `Instant`. Inlining
`TimerData` for this description, I think `setTimer(TimeDomain, Instant)` is OK
for setting an anonymous "wake up" as we use it today, while
`deleteTimer(TimeDomain, Instant)` should be removed.

Add setTimer and deleteTimer by ID in TimerInternals
For users, timers will have IDs. This is a step towards
that API; our current API treats the timer's timestamp
as its ID, more-or-less. We can leave that API or not. This
change adds the more general API.
