Dump a complete report from a performance run, as JSON

Browse Source 
When SHELL_PERF_OUTPUT is set, instead of just dumping out the metrics, dump
a more complete report with:

 - Event descriptions
 - Metric descriptions and value
 - Event log

Helper functions shell_perf_log_dump_events() and shell_perf_log_dump_log()
are added to ShellPerfLog to support this. The gnome-shell wrapper is adapted
to deal with the changed report format.
