Review Comment:
I updated the comments and cleaned up the logic in
`setAndVerifyOutputTimestamp`, I think it should be much clearer how its
supposed to work now.

> Currently processing time timers ignore the outputTimestamp and instead use
> the input watermark at the time they fire. This is wrong because the input
> watermark can have advanced arbitrarily far past the actual output timestamp
> when it fires.
> The correct behavior should be to instead use the outputTimestamp the timer
> was configured to fire with.
