[LargeIconService] Allow decoding of images in the service

Previously, LargeIconService only returned raw results. This is
advantagous for some clients that cache (or in other way need to use)
raw image data as encoding back is expensive. Still, many clients of the
service need to do the decoding on their side.

This CL adds another API function with the same behaviour that returns
a decoded gfx::Image if available. It leaves renaming the existing
function, callback, and result struct to a follow-up CL.
