LibGfx: Re-work the abstractions of sending image for decoding over IPC

Browse source 
Originally I simply thought that passing file paths is quite OK, but as
Linus pointed to, it turned out that passing file paths to ensure some
files are able to be decoded is awkward because it does not work with
images being served over HTTP.

Therefore, ideally we should just use the MIME type as an optional
argument  to ensure that we can always fallback to use that in case
sniffing for the correct image type has failed so we can still detect
files like with the TGA format, which has no magic bytes.
