UI: Small Changes to Graph Editor Active Vertex Panel

- X / Y value orders are all consistent, between handles and the keyframe.
- Values are labeled consistently, with just "Frame" and "Value"
- The more important type property that can affect the others comes first.
- The "type" property provides nice visual separation between the
handle properties.
