62173a1569 Introducing fabric/mounting module
Summary:
ShadowView, ShadowViewMutation, and Differentiator were decoupled to separate module.
That enables us to use ShadowView more widely without facing a circular dependency problem.

01af828d16 Fabric: Fixed possible race condition in ShadowTree::complete
Summary: Quite obviously, having a `complete` method which accepts only `newRootShadowNode` was a baaad idea. When we `complete` or `commit` we always have to have two nodes (before and after). And only after layout and right before swapping (and acquiring the mutex) we have to verify that *current* root node is still the same as it was when we initialized the transaction (if not, we have to abort).

4ce57cb7c7 Fabric: Passing size constraints as part of starting Surface
Summary:
Size constraints are essential part of the running Surface, decoupling them from starting process means that we will have to perform additional commit later.
This and previous couple diffs fix a problem with initial zero size of the surface and following visible "jumpy" relayout.

b8947c459f Fabric: ShadowTree::synchronize and reliable constraintLayout
Summary:
New `ShadowTree::synchronize` method allows to perform operations on ShadowTree without a risk of an unsuccessful commit. To make it happen, the `commitMutex_` is now recursive and `synchronize` acquires it before calling the callback.
Using that we finally can implement reliable `constraintLayout`.

b9850844a5 Fabric: constraintLayout is now return boolean
Summary:
Setting the right expectations: setting layout constraints might fail. Nothing really changed.
Implementing a reliable `constraintLayout` which locks instead of returning immediately requires some additional work and new/additional API.

c69313fc52 Fabric: Start/stop Surface calls were moved down to C++ layer
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`.

c25d5948a5 Fabric: Exposing EventEmitter's ownership model as a shared_ptr
Summary:
As we did in the previous diff, here we implemented `EventEmitter`'s ownership model as a `shared_ptr`. This change fixes problem with leaking `WeakObject`s which happens on hot-reload.

So, in short:
 * `EventTargetWrapper` object owns `jsi::WeakObject` that can be converted to actual `jsi::Object` that represent event target in JavaScript realm;
 * `EventTargetWrapper` and `jsi::WeakObject` objects must be deallocated as soon as native part does not need them anymore;
 * `EventEmitter` objects retain `EventTarget` objects;
 * `EventEmitter` can loose event target object in case if assosiated `ShadowNode` got unmounted (not deallocated); in this case `EventEmitter` is loosing possibility to dispatch event even if some mounting-layer code is still retaining it.

Summary:

Now it's clear that we don't need to store/handle ShadowTree objects as `shared_ptr`s; Scheduler should own it. This diff changes that to using unique_ptr and removes a base class of ShadowTree.

0792fba63f Fabric: Using ShadowView instead of ShadowNode in Mutations
Summary:
@public
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.
