Valentin Shergin d94a9e2640 Fabric: Composing YGNode object inside ShadowNode to avoid memory allocation overhead
Summary:
Given that fact that life-time of YGNode and ShadowNode objects must be idential and that we always allocate ShadowNode on heap,
we can embed YGNode object right inside ShadowNode object and use pointer to it safely.
That allows us to save additional memory allocation for every single layoutable shadow node! Whoo-hoo!

Valentin Shergin caaea38ad9 Fabric: Using unique_ptr for storing YGNode inside YogaLayoutableShadowNode
Summary:
I recently realized (Thanks David!) that we should not use `shared_ptr` for storing YGNode*
because ShadowNode does not share ownership of the Yoga node with anybody.
So the lifecycle of shadow node and yoga node must be synchronized (this is already the case but changing to unique_ptr makes this explicit and a bit more performant).

Valentin Shergin 10c5368c37 Fabric: Fixed issue where root shadow node does not layout itself
Summary: Conceptually, it always must be node owner's responsibility, but for the root node, we have to make an exception because there is no another parent node and there is no another component which has access to YogaNode.

Valentin Shergin f8ab0e0b08 Fabric: YogaLayoutableShadowNode::enableMeasurement() enables custom measuring for Yoga based shadow nodes
Summary:
YogaLayoutableShadowNode::enableMeasurement() connects Yoga's measuring API and Fabric measuring API.
`enableMeasurement` should be called for leaf Yoga nodes with custom content which should be measured manually during layout.

Valentin Shergin 98b4747041 Fabric/View: Debug printing logic in YogaLayoutableShadowNode was moved to superclass
Summary:
It's more useful and consistent now because:
 - We print compound layout metrics from the correct storage (not from Yoga nodes);
 - It works fro any kind of layout now (but we still have just one);
 - It's much clear and straight-forward.
