[NUI] Apply comments at VisualBase (phase 1)

Apply some comments that report at PR #6079

- `Color.A` getter apply `Opacity` changeness
- Make `VisualFittingMode` have no effect for `ColorVisual` and `BorderVisual`
- `GetVisualProperty` return valid value after call `GetCurrentVisualProperty`
- Make `VisualBase` class as abstract. Let we don't allow to call this class constructor.
