glsl/glcpp: Add explicit error for "#define without macro name"
Previously, glcpp would emit an error like this if <EOF> happened to occur
immediately after the "#define", but in general would just get confused,
(leading to un-helpful error messages).
To fix things to generate a clean error message, we do a few things:
1. Don't require horizontal whitespace immediately after #define
2. Add a production for the error case, (DEFINE_TOKEN followed
immediately by a NEWLINE token).
3. Make the lexer reset to the <INITIAL> state after every NEWLINE.
This 3rd point prevents the lexer from getting so confused and generating
further spurious errors in the file because it was stuck in the <DEFINE> start
condition.
We also drop the similar error message from the <EOF> rule since the
newly-added rule will have already printed the error message.
