Mandar Kulkarni d787775806 LibWeb: Skip decoding favicon.ico if downloaded data is empty ...

Some sites don't have favicon.ico, so we may get 404 response.
In such cases, ResourceLoader still calls success_callback.
For favicon loading, we are not checking response headers or payload
size.
This will ultimately fail in Gfx::ImageDecoder::try_create().

So avoid unnecessary work by returning early, if data is empty.
