[Feature] Support `measureContent(...)` for Nitro Views

[mrousavy]

Feature Request/Enhancement

Yoga allows us to override this method:

/*
 * Measures the node (and node content, probably recursively) with
 * given constrains and relying on possible layout.
 * Default implementation returns zero size.
 */
virtual Size measureContent(const LayoutContext &layoutContext, const LayoutConstraints &layoutConstraints) const;

This requires you to also override ConcreteViewShadowNode::BaseTraits() and add these two traits:

react::ShadowNodeTraits HybridCameraViewNode::BaseTraits() {
  auto traits = ConcreteViewShadowNode::BaseTraits();
  traits.set(react::ShadowNodeTraits::LeafYogaNode);
  traits.set(react::ShadowNodeTraits::MeasurableYogaNode);
  return traits;
}

We can override this in Nitro, and implement it in a static Swift/Kotlin method that receives the props. Something like this:

class HybridCameraView: HybridCameraViewSpec {
  // ...

  static func measureContent(props: CameraProps,
                             layoutContext: LayoutContext,
                             layoutConstraints: LayoutConstraints) -> Size {
    return Size(width: 100, height: 50)
  }
}

Are there any existing workarounds?
