perf tools: Fix attributes for '{}' defined event groups Fixing events attributes for groups defined via '{}'. Currently 'enable_on_exec' attribute in record command and both 'disabled ' and 'enable_on_exec' attributes in stat command are set based on the 'group' option. This eliminates proper setup for '{}' defined groups as they don't set 'group' option. Making above attributes values based on the 'evsel->leader' as this is common to both group definition. Moving perf_evlist__set_leader call within builtin-record ahead perf_evlist__config_attrs call, because the latter needs possible group leader links in place.

perf tools: Fix 'disabled' attribute config for record command Currently the record command sets all events initially as disabled. There's non conditional perf_evlist__enable call, that enables all events before we exec tracee program. That actually screws whole enable_on_exec logic, because the event is enabled before the traced program got executed. What we actually want is: 1) For any type of traced program: - all independent events and group leaders are disabled - all group members are enabled Group members are ruled by group leaders. They need to be enabled, because the group scheduling relies on that. 2) For traced programs executed by perf: - all independent events and group leaders have enable_on_exec set - we don't specifically enable or disable any event during the record command Independent events and group leaders are initially disabled and get enabled by exec. Group members are ruled by group leaders as stated in 1). 3) For traced programs attached by perf (pid/tid): - we specifically enable or disable all events during the record command When attaching events to already running traced we enable/disable events specifically, as there's no initial traced exec call. Fixing appropriate perf_event_attr test case to cover this change.
