Bug 1551088 - Part 6. Make image decoders use accelerated methods for swizzling and premultiplication. r=tnikkel

The PNG decoder lacks fast implementations for swizzling/unpacking
inside the library, and both PNG and WebP may need to perform
premultiplication due to the alpha channel. This patch adds a new filter
allowing us to take advantage of our accelerated implementations to
perform these transformations on their behalf.
