fix(chapi-ast-c): modify C.g4 to support multiple macro declarations #24

The C.g4 file in chapi-ast-c was modified to support multiple macro declarations. The previous implementation only allowed for a single declaration, but now it supports multiple declarations separated by StringLiterals or singleLineMacroDeclarations. This change improves the flexibility and functionality of the C.g4 file.
