perf scripts python: exported-sql-viewer.py: Add call tree
Add a new report to display a call tree. The Call Tree report is very
similar to the Context-Sensitive Call Graph, but the data is not
aggregated. Also the 'Count' column, which would be always 1, is replaced
by the 'Call Time'.
Committer testing:
