    R: @jkff (I'll grab a committer later, but your contributions are thing affected)
    The only substantive aspect of this change is the move of the timer internals directly
into `ProcessFn`. I think this is right or at least the right compromise for many reasons.
     - `TimerInternals` is really runner-facing; we don't want that interface in the SDK.
     - Changes to `TimerInternals` incur worker compatibility concerns, so getting it into
runners-core is a win. (I have to change it soon, so I am trying to make my life easier)
     - `DoFnTester` doesn't actually support timers at all, so it didn't make sense for them
to be in there.
     - When `DoFnTester` does support timers, it is trivial to make its own priority queues,
and it will also want to offer greater insight via a richer `TestingTimerInternals` sort of
implementation, which needs not implement the same interface, etc.
