ARROW-16643: [C++] Fix warnings for clang-14

[wesm]

The following code in arrow/util/small_vector_benchmark.cc generates -Wreturn-stack-address in clang-14. It might be better to fix but suppressing for now:

template <typename Vector>
ARROW_NOINLINE int64_t ConsumeVector(Vector v) {
return reinterpret_cast<intptr_t>(v.data());
}
template <typename Vector>
ARROW_NOINLINE int64_t IngestVector(const Vector& v) {
return reinterpret_cast<intptr_t>(v.data());
}

Filed https://issues.apache.org/jira/browse/ARROW-16644 so we don't forget about the suppression.

That AppVeyor issue should be fixed by #13191
