bindings: Support 'undefined' keyword as replacement of 'void'
Makes the IDL lexer / parser support 'undefined' keyword.
The bindings code generator also accepts 'undefined' as replacement
of 'void', but no further features are yet supported. 'undefined'
cannot be used as a default value for example at this point.
