Subject: [PATCH v1 1/2] trace: add new file under include/trace/stages/ for perf/bpf
when experiment change for trace operation, the files under
include/trace/stages/ will be changed, perf/bpf trace may compile fail.
add new file stage_perf_call.h and stage_bpf_call.h under
include/trace/stages, it will make sure no missing change when expriment.
