LibGfx+Ladybird+Userland: Don't sniff for TGA images with only raw bytes
Because TGA images don't have magic bytes as a signature to be detected, instead assume a sequence of ReadonlyBytes is a possible TGA image only if we are given a path so we could check the extension of the file and see if it's a TGA image. When we know the path of the file being loaded, we will try to first check its extension, and only if there's no match to a known decoder, based on simple extension lookup, then we would probe for other formats as usual with the normal sniffing method.
