GPencil: Add support to display the material name in selected strokes

2D artists have requested a way to see in viewport the name of the material assigned to a stroke. This is a special request for 2D animation and required to manage complex drawings with multiple materials on it. We don't need add a separate option for this in the panel.

Now, when enable Name option in the Viewport Display panel, when you select a stroke in edit mode, the name of the material is displayed near the first point selected.
