Remove sprite-* benchmarks

sprite-sequence isn't really of much use. It was written to demonstrate
that SpriteSequence isn't really very performant.

sprite-image was written to compare against SpriteSequence, and while a little
more useful, the implementation is inherently flaky for two reasons:

* It uses Math.random to calculate wait times
* It uses PauseAnimation, which means that the test periodically doesn't
  run at full throttle

Since it isn't terribly useful as a benchmark for regression testing,
let's simply remove the two of them.
