perf scripts python: exported-sql-viewer.py: Add copy to clipboard
Add support for copying to clipboard. Two menu options are added to copy the
selected rows / columns with normal spacing, or as comma-separated-values.
In the case of trees, only entire rows can be copied.
Comitter testing:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Select the lines, press control+C and on the same terminal,
press control+shift+V and voilà:
