LibGUI: Ensure unknown emoji have a set display order

Browse Source 
Currently, we use code point values as a tie break when sorting emoji by
display order. When multiple code point emoji are supported, this will
become a bit awkward. Rather than dealing with varying code point length
while sorting, just set a maximum display order to ensure these are
placed at the end.
