Module preprocessor 

C Preprocessor simulation layer

This module provides a lightweight preprocessing layer that handles common C macros without requiring actual header files. Unlike a real preprocessor, this doesn’t expand macros textually but instead helps tree-sitter parse code that uses common macro patterns.

Key strategies:

1. Macro recognition: Identify and annotate common macro patterns
2. Attribute simulation: Convert attribute and similar to parseable form
3. Kernel macro handling: Special support for Linux kernel macros
