  CanvasBase::postProcessPixelBufferResults() takes an rvalue Ref<PixelBuffer> 
it never moves

Reviewed by Gerald Squelart.

postProcessPixelBufferResults() took Ref<PixelBuffer>&& but never moved or
stored it: it forwarded to 
CanvasNoiseInjection::postProcessPixelBufferResults(),
which takes PixelBuffer&. std::forward on the non-deduced Ref<PixelBuffer> was
just a cast to rvalue reference. The sole caller passes a PixelBuffer&, so
every WebGL getImageData() materialized a temporary Ref for the duration of
the call, paying a ref()/deref() pair for nothing.

Take PixelBuffer& instead. No behavior change.
