[shaders] Make updating uniforms controls more efficient.

- Add needsRAF() and onRAF() to the UniformControl interface.
- Implement all those methods on all the uniform controls.
- Move fps module to infra-sk.
- Add uniform-fps-sk control which displays the frames per second.
- Switch shader-app-sk to use needsRAF() and onRAF() to avoid
  calling _render() on every requestAnimationFrame.
