LibGfx: Remove Gfx::ImageDecoder::bitmap() in favor of frame(index)

To transparently support multi-frame images, all decoder plugins have
already been updated to return their only bitmap for frame(0).

This patch completes the remaining cleanup work by removing the
ImageDecoder::bitmap() API and having all clients call frame() instead.
