selftests/bpf: add batched tp/raw_tp/fmodret tests

Browse source

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.
