Subject: [PATCH 01/43] #194 define preprocessor

feat: Add DirectX preprocessor for handling #define, #ifdef, #include, and related directives

refactor: Integrate preprocessor into DirectX lexer

refactor: Update DirectX backend init to include preprocessing pipeline

test: Add tests for DirectX preprocessor functionality

fix: Improve error handling for invalid directives in preprocessor

Subject: [PATCH 29/43] #194 define preprocessor .... #'commit30?

Mocking os.path.exists: I added the @patch("os.path.exists", return_value=True) decorator to mock os.path.exists for all the test methods that deal with file inclusion. This ensures that file existence checks return True during tests.

Raising ValueError for Undefined Macros: I updated the expand_macros method to raise a ValueError when undefined macros are encountered.
