LibGfx+LibUnicode: Support specifying the path to search for emoji

Browse source 
Similar to the FontDatabase, this will be needed for Ladybird to find
emoji images. We now generate just the file name of emoji image in
LibUnicode, and look for that file in the specified path (defaulting to
/res/emoji) at runtime.
