perf metrics: Sort the Default metricgroup

Browse source

The new default mode will print the metrics as a metric group. The
metrics from the same metric group must be adjacent to each other in the
metric list. But the metric_list_cmp() sorts metrics by the number of
events.

Add a new sort for the Default metricgroup, which sorts by
default_metricgroup_name and metric_name.

Add is_default in the struct metric_event to indicate that it's from
the Default metricgroup.

Store the displayed metricgroup name of the Default metricgroup into
the metric expr for output.
