This is more than a cosmetic change: adding "GTK" prefix in wxComboBox and not
doing it in wxChoice in r64436 broke the event generation for wxComboBox as it
didn't override wxChoice methods any longer but defined its own (useless) ones.
Using the same name for the methods in both classes notably fixes unexpected
event generation from wxComboBox::SetSelection().
Closes#12568.

Add a lot of tests for many wx GUI classes.
Add tests using the new wxUIActionSimulator class but disable them under OS X
as too many of them currently fail there.
Refactor the test suite to make organizing the existing tests and adding the
new ones easier.
Improve documentation using the information gathered while testing the
classes. Also update the documentation of the testing system itself.
