LibGfx/TIFF: Add an intrinsic way to get the exportable name of Enums

Browse source 
The `TIFFType` enum is exported with a different name to C++. This
change of behavior was handled by manually setting the parameter of a
function. However, we will soon need the exported name in more places,
so let's make it a property of the Enum itself.
