RUMM-2298 Correctly resolve ShapeStyle opacity in Wireframes

[mariusc83]

What does this PR do?

Previously we were resolving the ShapeStyle opacity from the View.backround which is not correct. For example a TextView can use a transparent background but still have a visible content. We need to resolve this attribute directly from the View.alpha property.
