This commit registers the va_list language item within the gccrs compiler. This involves adding a corresponding enum value for VaListImpl in the header file and registering it in the compiler’s language item management system. This is a necessary step for gccrs to correctly handle C’s variadic function arguments (...) when interacting with C code or when implementing similar features.
