Message:

Use the Accelerate framework to optimize FEColorMatrix operations
​https://bugs.webkit.org/show_bug.cgi?id=170518

Reviewed by Tim Horton.

On macOS and iOS, we can use the Accelerate framework (vImage) to do color matrix
math to optimize color matrix, hue rotate, saturation and luminosity to alpha filters.

Change ImageBuffer::getUnmultipliedImageData() and getPremultipliedImageData() to
return the size of the returned Uint8ClampedArray in physical pixels, because we
need to pass that to vImage.
