[IMPROVEMENT] Useless `[ExecuteAlways]` and `Update()` calls in CanvasSliderVisuals, editor slider value not sync in playmode

[anonymous2585]

Describe the problem

The script CanvasSliderVisuals uses an Update() function to do things in the editor. https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity/blob/e30b350c131501084a4f9003cba1361248717f66/org.mixedrealitytoolkit.uxcore/Slider/Visuals/CanvasSliderVisuals.cs#L166

I fell it is not necessary in this case, a OnValidate() function should do the job. The [ExecuteAlways] could then be removed, improving in editor performances.

Moreother, the handle position is not updated when modifying the slider value from the inspector in playmode. This is different from the classic Unity UI. I d'like the behaviour in editor to be the same as the Unity UI slider.

Describe the solution you'd like

• Replace the [ExecuteAlways] and Update() with an OnValidate() function or other Unity editor tools.
• Make the editor slider value sync in playmode (and send value changed events like Unity UI)

Low priory issue, worth investigating.
