This commit improves error reporting in gccrs by ensuring that empty path expressions, such as those starting with ::, trigger a diagnostic. Previously, the parser might silently return an error node, leading to internal compiler errors (ICEs) later in the process. The redundant guard in parse_stmt_or_expr was also removed. New test cases empty_path2.rs and empty_path3.rs are added.
