perf scripts python: exported-sql-viewer.py: Add ability to shrink / enlarge font

Browse source 
Shrinking the font allows more information to display.

Committer testing:

Works, tested with the convenient Control+Shift+'+' and Control+'-' as
well with the more cumbersome top menu "Edit" + "Enlarge/Shrink font"
options.
