Summary:
This PR follows the work started in #6431 but instead of implementing the snapshot for Android, will just allow that feature to be implemented by a third party library.
The missing feature is the ability to resolve a View for a given tag integer. which is now possible with a `addUIBlock` on the `UIManagerModule` method where you give a `UIBlock` instance (a new class) that implements a `execute(NativeViewHierarchyManager)` function.
This is already possible in iOS API. a third party can use the `addUIBlock` too.
I have kept the name `addUIBlock` so it's the same as in the [iOS' API](https://github.com/facebook/react-native/search?q=addUIBlock&type=Code&utf8=%E2%9C%93).

With this PR a third party lib can now do...
```java
UIManagerModule uiManager = reactContext.getNativeModule(UIManagerModule.class);
uiManager.addUIBlock(new UIBlock() {

Summary:
When we hit the back button and unmount the ReactRootView, we tell JS to unmount the application root node, which causes JS to asynchronously come back and tell the UIManager to drop the corresponding root view.
This issue was that by the time JS gets back to us, we likely will have already paused the UIManager frame callback which means the view unmounting never actually happens: it just gets stuck in the queue.
The solution is to immediately execute batches when they are enqueued when the frame callback isn't running.

Summary:Creating views shouldn't have side effects so we can start doing them before the end of a batch. In order to limit the effect on framerate, we stop executing these create view operations after we've passed halfway through the frame.
Note, this doesn't seem to work yet for nodes: I'll address that in a followup diff.

Summary:This is the first from the series of PRs I'm going to be sending shorty that would let Animated.js animations to run off the JS thread (for Android only).
This PR introduce a new native module that will be used for offloading animations - NativeAnimatedModule. It has a simple API that allows for animated nodes management via methods like: create/drop animated node, connect/disconnect nodes, start animation of a value node, attach/detach animated from a native view.
Similarly to how we handle UIManager view hierarchy updates we create a queue of animated graph operations that are then executed on the UI thread. This isolates us from problems that may be caused by concurrent updates of animated graph while UI thread is "executing" the animation.
The most important class NativeAnimatedNodesManager.java implements a management interface for animated nodes graph as well as implements a graph traversal algorithm that is run for each animation frame. For each animation frame we visit animated nodes th

Summary: public This patch adds an alternative UIImplementation based on an idea of creating UI hierarchy off-the-main-thread (everything but Views), flattening ReactShadowNode hierarchy and displaying it within a single View when possible. While NativeViewHierarchyOptimizer allows removing layout-only RCTViews, this allows removing RCTView, RCTText and RCTImage.
This is an initial bare-bones implementation that doesn't really draw anything, only lays out the shadow nodes. Followup diffs will add missing features.

Summary: public NativeViewHierarchyManager.createView() takes int rootViewTag which is only used to resolve ThemedReactContext, but we already have it resolved before we enqueueCreateView, so we can just pass it directly. This makes mRootViewsContext tag -> to ThemedReactContext mapping unnecessary in NativeViewHierarchyManager. Makes the class simpler.

Summary: public I need to extend NativeViewHierarchyManager to support a richer set of operations on Views, and those operations needs to be ran in UI thread.
Existing UIViewOperationQueue doesn't know about those operations, so I need to extend it too to allow them. This patch is making the class constructor protected to allow subclassing it from another package. Should not have any functional changes.

Summary: public There is really no reason NativeViewHierarchyManager.addRootView() should be performed synchroniously when called from background thread, as long as it is executed before every other command in UIViewOperationQueue, and we can ensure that by putting add view command at the front of the queue. When that happpens, the queue should always be empty anyway, but it's best to be safe.
This eliminates an unnecessary blocking call and should overall make the code simpler and safer (Semaphores can timeout).

Summary: public UIManageModule creates AnimationRegistry but never uses it, this diff moves it to NativeViewHierarchyManager who owns it. UIViewOperationQueue depends on AnimationRegistry to perform some of the enqueued operations, so it accessed it through a getting in NativeViewHierarchyManager. This will also make sure NativeViewHierarchyManager. and UIViewOperationQueue operate on the same AnimationManager (previously, that wasn't really enforced). This is needed so I can move away UIViewOperationQueue creation off the UIManagerModule. This diff should have no functional changes whatsoever.

Summary: public
Native view recycling implementation based on limited pools of views.
In this diff I introduced new UIManager method: dropViews. Instead of removing views from tag->view maps when they are detached we keep them there until we get a call to dropViews with the appropriate tag. JS may keep a pool of object and selectively decide not to enqueue drop for certain views. Then instead of removing those views it may decide to reuse tag that has been previously allocated for a view that is no longer in use.
Special handling is required for layout-only nodes as they only can transition from layout-only to non-layout-only (reverse transition hasn't been implemented). Because of that we'd loose benefits of view flattening if we decide to recycle existing non-layout-only view as a layout-only one.
This diff provides only a simple and manual method for configuring pools by calling `ReactNativeViewPool.configure` with a dict from native view name to the view count. Note that we may not want recycle all the views (e.g. when we render mapview we don't want to keep it in memory after it's detached)
