changelog: [internal]
If nodesManager has the information if animated node is managed by Fabric, we can't decide if the operation queue should be flushed before it is flushed. Therefore, keep the information about animated nodes inside a set instead of nodesManager.
For simplicity, I will refer to class `RCTNativeAnimatedTurboModule` as *NativeAnimated* and to `RCTNativeAnimatedNodesManager` as *NodesManager*
Notice that each call to *NativeAnimated* is queued up in `_operations` or `_preOperations`. When the queues are flushed, only then methods are called on `RCTNativeAnimatedNodesManager`.
There are two mechanisms that flush operations.
One is triggered by `RCTMountingManager` before mounting operations are applied and after they are applied. This works fine but is important to paint the picture.
The second mechanism is inside `[RCTNativeAnimatedTurboModule startAnimatingNode]`. It flushes the queues for Fabric nodes only (not sure why Fabric nodes only, I couldn't find any explanation in old diffs). It checks with *NativeAnimated* if a node is managed by Fabric. Keep in mind, *NodesManager* only knows about the nodes when the queues have been flushed.
Exampe:
JavaScript calls methods on *NativeAnimated*.
For example:
1. `createNode`
2. `connectAnimatedNodeToView`
3. `startAnimatingNode`. (here, the queues should be flushed, since we are in Fabric)
All of these operations are queued up and for as long as `RCTMountingManager` executes mounting, all proceeds as expected.
But if those operations happen after mounting phase, `startAnimatingNode` will not flush the operations queues, because it can't tell if nodeTag is managed by fabric or it isn't. This is because *NodesManager* hasn't been notified about any new nodes.

Summary:
Main change is to the property diffing - we now use the last known props set on the view rather than the default props to compute the diff. This requires exposing a `getProps` method on all view components which should be fine I think.
I also realized that in more complex animations with multiple nodes, the node that the animation starts on might not be connected to a view, so we don't know if it's fabric just based on that, so we have to do a recursive search through the children to find if there are any that are associated with a fabric view to decide we should start the animation immediately. Unfortunately there can still be a timing gap here since the animated API is async and the uimanager API is sync - I'll need to change the animated API to be sync to completely fix this.

Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.
Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.
Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.
Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101
In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.
As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.
I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.
You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101
[GENERAL][FEATURE][Native Animated] - Added support for animated tracking to native driver. Now you can use `useNativeDriver` flag with animations that track other Animated.Values

Summary:
This diff attempts to fix a number of iOS native animation bugs related to improper node invalidation and a race with view creation. The major issues were presented in #9120 as problems 3 and 3b, but I'll recap here:
The invalidation model we use is overly complicated and incomplete. The proper combination of `_needsUpdate` and `_hasUpdated` will result in nodes values being recomputed. However, we do not invalidate nodes in all the places we should, e.g. if we create a new view and attach it to an existing value node (see example in #9120). This diff chooses to remove the `_hasUpdated` flag, and simply relies on the `_needsUpdate` flag to mark a node as dirty.
We mark nodes as dirty when they are:
- created
- updated
- attached to new parents
- detached from old parents
- attached to a view
Calling `updateNodeIfNecessary` will, if necessary, compute all invalidated parent values before recomputing the node value. It will then apply the update, and mark the no

Summary:
Currently on iOS animations are being performed on the JS thread. This ports animations over to the native thread and performs them natively. A lot of this work has already been done on Android, but this PR enables a few animation nodes that Android doesn't yet support such as Transform, Multiplication, and Addition nodes.
Also there is a demo of the native animations added to the UIExplorer app.
