girepository: Add missing includes of corresponding headers

Make sure that each C file in `girepository/` includes its corresponding
header file (if such a file exists).

This ensures that the first declaration the compiler sees for each
function contains the symbol visibility macros. This fixes symbol export
(`dllexport`) on Windows platforms.
