perf scripts python: export-to-sqlite.py: Export Intel PT power and ptwrite events
The format of synthesized events is determined by the attribute config. For the formats for Intel PT power and ptwrite events, create tables and populate them when the synth_data handler is called. If the tables remain empty, drop them at the end. The tables and views, including a combined power_events_view, will display automatically from the tables menu of the exported exported-sql-viewer.py script. Note, currently only Atoms since Gemini Lake have support for ptwrite and mwait, pwre, exstop and pwrx, but all Intel PT implementations support cbr.
