kernel/trace: Introduce trace_probe_print_args and use it in *probes
print_probe_args is currently inplemented in trace_probe_tmpl.h and
included by *probes, as a result, each probe has an identical copy.
This patch will move it to trace_probe.c as an new API, each probe
calls it to print their args in trace file.
