Reafactored Lexer class to allow chaining. The full chain when parsing #if directive looks like this: Preprocessor -> MacroExpander -> DirectiveHandler -> MacroExpander -> DefinedFilter -> Tokenizer. This chain dynamically changes depending on the current context.
Also added an incomplete implementation of #if handling and ExpressionParser to illustrate how this design is supposed to work.

Using yy_scan_string, which flushes the old buffer does not work. GLSL requires that each input string is concatenated, but yy_scan_string treats each string individually. Added a custom YY_INPUT which maintains the continuity between each string.

Drastically simplified Input class. Now most of the heavy lifting is done by in-built yy_scan_string and yy_scan_bytes. Comment handling will be done by the lexer.

Punted on bison parser. It was turning out to be more complicated than necessary. Manual parsing combined with a flex lexer is easier.
