Use GraphicContext::drawImageBuffer in FEBlend

Get rid of the "local" implementation of the blend modes in favor of the
Skia implementation.
Still uses the ARM NEON specific implementation for when
ARM_NEON_INTRINSICS is enabled.
Also change so that createImageFilter uses WebCoreCompositeToSkiaComposite
to map to the Skia Xfermode.

Inspired by WebKit commit http://trac.webkit.org/changeset/170433 by
Dirk Schulze.
