[NUI]CanvasView: Add BoundingBox property (#2995)

Add BoundingBox property that uses Dali::CanvasRenderer::Drawable::GetBoundingBox api.

+)The float type Rectangle class is not ready yet.
Therefore, it transmits data in Vector4 class.
This type should later be changed to the appropriate data type.
