Introduce a new metricgroup, Default, to tag all the metric groups which will be collected in the default mode. Add a new field, DefaultMetricgroupName, in the JSON file to indicate the real metric group name. It will be printed in the default output to replace the event names. There is nothing changed for the output format. On SPR, both TopdownL1 and TopdownL2 are displayed in the default output. On ARM, Intel ICL and later platforms (before SPR), only TopdownL1 is displayed in the default output.
