[PATCH V2 1/2] bpf: control the trace data output on current cpu when perf sampling

This patch adds the flag sample_disable to control the trace data output process when perf sampling. By setting this flag and integrating with ebpf, we can control the data output process and get the samples we are most interested in. The bpf helper bpf_perf_event_sample_control() can control the
