Tests/LibGfx: Actually test image decoders in TestImageDecoder

Browse source 
We were passing raw Gfx::Bitmap objects into the various image decoders
instead of encoded image data. This made all of them fail, but the test
expectations were set up in a way that aligned with this outcome.

With this patch, we now test the codecs for real. Except ICO, since we
don't have an ICO file handy. That's a FIXME.
