ImageDecoder+LibImageDecoder+LibWeb: Support animations in ImageDecoder

Browse source 
The ImageDecoder service now returns a list of image frames, each with
a duration value.

The code for in-process image decoding is removed from LibWeb, an all
image decode requests are sent out-of-process to ImageDecoder. :^)

This won't scale super well to very long and/or large animations, but
we can work on improving that separately. The main goal here is simply
to stop doing any image decoding inside LibWeb.

Fixes #5165.
