Utilize bpf_modify_return_test_tp() kfunc to have a fast way to trigger tp/raw_tp/fmodret programs from another BPF program, which gives us comparable batched benchmarks to (batched) kprobe/fentry benchmarks. We don't switch kprobe/fentry batched benchmarks to this kfunc to make bench tool usable on older kernels as well.
