compiler: Remove instance Binary Charwip/no-binary-char
It is generally not a good idea to serialise strings as [Char] into interface files,
as upon deserialisation each of these would be turned into a highly memory inefficient
structure mostly composed of cons cells and pointers.
If you really want to serialise a Char, use the SerialisableChar newtype.
