perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()
...
Since it's only used for checking ->pipe_output, we can pass the result
directly.
Now the perf_evlist__prepare_workload() don't have a dependency of
struct perf_record_opts, it can be called from other places like perf
stat.

perf evlist: Pass struct perf_target to perf_evlist__prepare_workload()
...
It's a preparation step of removing @opts arg from the function so that
it can be used more widely.

perf evlist: Remove cpus and threads arguments from perf_evlist__new()
...
It's almost always used with NULL for both arguments. Get rid of the
arguments from the signature and use perf_evlist__set_maps() if needed.

perf evlist: Set the leader in the perf_evlist__config method
...
Since we need to ensure the leader is set before configuring the
evsel perf_event_attrs.
Reducing the boilerplate needed by tools, helping, for instance,
'perf trace', that wasn't setting the leader.

perf evsel: Update sample_size when setting sample_type bits
...
We use evsel->sample_size to detect underflows in
perf_evsel__parse_sample, but we were failing to update it after
perf_evsel__init(), i.e. when we decide, after creating an evsel, that
we want some extra field bit set.
Fix it by introducing methods to set a bit that will take care of
correctly adjusting evsel->sample_size.
