Workbench: Viewport AA Preferences

In recent changes the viewport_quality setting was not working what
users expected. This change will separate the anti-aliasing method that
is being used.

We now have three settings:

* scene.display.render_aa: Will be used during `Render Image`.
* scene.display.viewport_aa: Will be used during `Viewport Render Image`.
* userpref.viewport_aa: Will be used in the 3d view.

The viewport_quality setting has been replaced by the viewport_aa
setting as it was the only thing in currently controlled.
