LibGfx/WebP: Remove pointless decode_webp_chunk_VP8L() function

The one caller checked the chunk type, so the VERIFY() for that did
nothing.

The VERIFY() for vp8l data only being in files that start with
VP8L or VP8X chunks wasn't completely useless, but also not very
useful.

Remove the now-unused context parameter of decode_webp_image_data().
