[clang][sema] consolidate diags for incompatible_vector_* (#83609)
removing the additions of `err_vec_builtin_non_vector_all` & `err_vec_builtin_incompatible_vector_all` caused by #83077. Instead adding a select option to `err_vec_builtin_non_vector` & `err_vec_builtin_incompatible_vector` to account for uses where there are more than two arguments.
