Include an Overview tab in Toolkit Trace Log Analysis data

The Toolkit trace log analysis gives a lot of detailed data for resources used by each program called during the trace, but sometimes it is difficult to get an overview for the whole trace.
A new "Overview" tab in the Trace Log Analysis section would meet this requirement and can include resources that are not currently reported by the TRLOG collection such as pool usage, VFA accesses, Copy on Write exceptions, tape accesses etc.
All these values are available in the ECB or its associated ECB resource monitor block, the following list was copied from PJ41593!
