Introduce arch_perf_sample__fprintf_synth_evt to add support for
printing arch specific synth event details. The process_event()
function in "builtin-script.c" invokes perf_sample__fprintf_synth() for
displaying PERF_TYPE_SYNTH type events.
if (attr->type == PERF_TYPE_SYNTH && PRINT_FIELD(SYNTH))
perf_sample__fprintf_synth(sample, evsel, fp);
perf_sample__fprintf_synth() process the sample depending on the value
in evsel->core.attr.config . Currently all the arch specific callbacks
perf_sample__fprintf_synth* are part of "builtin-script.c" itself.
Example: perf_sample__fprintf_synth_ptwrite,
perf_sample__fprintf_synth_mwait etc. This will need adding arch
specific details in builtin-script.c for any new perf_synth_id events.
Introduce arch_perf_sample__fprintf_synth_evt() and invoke this as
default callback for perf_sample__fprintf_synth(). This way, arch
specific code can handle processing the details.
