Valentin Shergin ec5b1fd259 Fabric: Optimized ShadowNode::replaceChild() with `suggestedIndex` argument
Summary:
@public
In most cases callsite knows probable index of replacing child node, hence it makes sense to provide this info to `replaceChild` to illuminate O(n) search in most cases.

Valentin Shergin e906d4cdc9 Simplifying child nodes management in YogaLayoutableShadowNode
Summary:
@public

This diff consists of many interdependent changes which support one simple idea: YogaLayoutableShadowNode is now using YGNode children to iterate on them (it previously relied on `ShadowNode::getChildren()`). All other changes are just an unavoidable consequence of that. Hence we don't need to filter child nodes every single time when we do layout anymore! The logic around `clone callback` is also drastically simpler now.
The new approach also implies that `LayoutableShadowNode` and `YogaLayoutableShadowNode` don't use `shared_ptr`s to refer to ShadowNode objects because new relationship does not imply ownership. No more `SharedShadowNode` objects in those two classes.

Valentin Shergin 62f9ced099 Fabric: Subtle changes that make GCC compiler happy
Summary:
@public
Most of them are legit issues which should not be compilable anyways (but Clang tolerates thems).

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.

Valentin Shergin b13d5beb11 Fabric: `LayoutableShadowNodeList::getChildren` renamed to `getLayoutableChildNodes`
Summary:
The previous name conflicts with the method with same (but with different semantic) name in `ShadowNode` class.
That was bad idea to use same name especially because the different semantic.

Valentin Shergin ee0cc6bbe7 Fabric: Implementing cloneAndReplaceChild() for ViewShadowNode
Summary:
First, LayoutableShadowNode::cloneAndReplaceChild() is now pure virtual. The default implementation was useless and confusing.
Second, cloneAndReplaceChild() is now fully implemented for ViewShadowNode, so fancy Yoga Concurrent layout *should* work now.
