Subject: [PATCH] tests: Add test running basic perf test

This test runs all of GNOME Shell using the headless backend inside a
mocked D-Bus environment. The basic test tests, well, basic things, like
the panel menu, the overview, showing the app grid view, as well as
going back to the session view.
