Reorganize OpenGL renderer tests

The new UI works just like ApiDemos. The label of the activities
declared in the manifest defines where they go in the UI.

For instance Draw/Circles will create an entry called Draw in the
first screen of the test app. Click the "Draw" item will launch
a new activity containing an item called "Circles".
