Summary:
Don't ask.
Really, all those descriptions from official docs like below are useless:
* `__bridge_transfer` Moves a Core Foundation pointer to Objective-C with transfer of the ownership to ARC.
* `__bridge` Transfers a pointer between Objective-C and Core Foundation with no transfer of ownership
All that is totally confusing and useless. At the end of the day, we only have to think about which additional `CFRetain` and `CFRelease` ARC will add or will not add for our pointers.
So, following official docs recommendation, we would like to add `__bridge_transfer` because of course, we do want to ARC managing the variable after we introduced it to ARC here. But we also want to have shared ownership of this. That's the key. If we use `__bridge_transfer` ARC will assume that this variable already retained once (because it exists) and will call CFRelease at the end of the scope. Right before that when we pass this variable down to call stack ARC will retain and then manage the variable according to the rest of the code. But still, from this point, we will have zero-balanced reference counter; the owning by `shared_ptr` bump is already compensated with `CFRelease` at the end of the scope. As soon as the rest of the code release the object, it will be incorrectly deallocated.
So, instead of using `__bridge_transfer` we have to use `__bridge`. That will indicate that *in this block* ARC does not manage the reference counter of the variable (which is kinda true because having `shared_ptr` inside the block already retains that) and will not add `CFRelease` at the end of the block.

Summary:
There is no need to make JS calls to start or stop React Native apps; Scheduler does it automatically. Yay!
With this change (because we have to change Scheduler API) we are starting slow process migrating away from using term `reactRootTag` when we refer to running a ReactNative app (aka Surface). We will use `surfaceId` instead. We plan to slowly and gracefully retire `reactTag` term entity replacing it with several appropriate entities specific for particular usage, e.g. `viewId` (some id which makes sense for mounting), `surfaceId`, `nodeId` (unique id representing nodes which were cloned from the original one), or `eventTarget`.

Summary:
The original design of RCTSurface implied that the Surface starts on initialization and stops on deallocation. Recently I realized that this not sufficient API in some cases when the application uses ARC with autorelease pools (that can postpone object deallocations, which is highly undesirable).
And that's simply handy to have those methods sometimes.

Summary:
Several reasons:
* We are fulfilling a promise that RCTScheduler is just a very thin interop proxy between C++ and Objective-C;
* We have to pass all parameters down to Scheduler anyway, so instead of creating all of them separately and then passing one-by-one, we consolidate them into Context created where we have all those values.
In the future, we probably will move it to some dedicated place.

This is quite a big diff but the actual meaningful change is simple: now we use ShadowView class instead of ShadowNode in mutation instructions.
Note:
* In some places (especially during diffing) we have to operate with ShadowNodeViewPair objects (which represents a pair of ShadowNode and ShadowView). The reason for that is that we cannot construct child ShadowViews from parent ShadowViews because they don't have any information about children.
* `ShadowTree::emitLayoutEvents` is now much simpler because ShadowView better represents the specifics of this kind of object.
* The code in RCTMountingManager also became simpler.
This change will allow us to implement more cool tricks soon.

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.
