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:
Not super clean, but not terrible.
Unfortunately this still relies on the old Paper UIManager calling delegate methods to flush the operations queues. This will work for Marketplace You since Paper will be active, but we need to fix this, along with Animated Events which don't work at all yet.
Random aside: it seems like taps are less responsive in fabric vs. paper, at least on iOS. There is a sporadic delay between the touches event coming in nativly to the JS callback invoking the native module function to start the animation - this will need some debugging.

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 changes the behaviour of natively driven animations in case the node that they are being run for has its value changed using `setValue` or as a result of an incoming event.
The reason for changing that is to match the JS implementation of `setValue` which behaves as described above (see relevant code here: 7cdd4d48c8/Libraries/Animated/src/AnimatedImplementation.js (L743))
**Test Plan:**
Use this sample app: https://snack.expo.io/B1V7RX9r-
Change: `USE_NATIVE_DRIVER` const between `true` and `false`.
See the animation stops regardless of the state of `USE_NATIVE_DRIVER` unlike before when it would stop only when `USE_NATIVE_DRIVER` was set to `false`

Summary:
There was an edge case where sometimes a view could be added and removed in the same batch so this caused issues because we ran `disconnectAnimatedNodeFromView` before `connectAnimatedNodeToView`. This separates restoring default values from `disconnectAnimatedNodeFromView` so we can run only `restoreDefaultValues` on the pre-operations queue and just do nothing in case the view doesn't exist (it is fine because we know it will be removed immediately).
**Test plan**
Tested that native animations still work properly in RNTester and tested that the edge case crash was fixed.

Summary:
Adds unit tests to the Native Animated implementation on iOS. This pretty much mirrors the tests we currently have on Android.
It also fixes 2 bugs I've found when adding the tests and pass the current time in `stepAnimation` instead of using `CACurrentMediaTime` to make testing easier.
- `stopListeningToAnimatedNodeValue` did not actually work at all, it should set the listener to nil.
- The finished value in the animation end callback was always true, this simplifies the `RCTAnimationDriver` interface to get rid of `removeAnimation` and fixes the end callback value.
**Test plan**
- Run the tests
- Make sure the UIExplorer example still works

---
Fixes a bug that happens when trying to use ScrollView with sticky headers and native `Animated.event` with `onScroll`. Made a few changes to the ListViewPaging UIExplorer example to repro https://gist.github.com/janicduplessis/17e2fcd99c6ea49ced2954d881011b09.
What happens is we need to be able to add multiple events to the same prop + viewTag pair. To do that I simple changed the data structure to `Map<prop+viewTag, List<AnimatedEventDriver>>` and try to optimize for the case where there is only one item in the list since it will be the case 99% of the time.
**Test plan**
Tested by reproducing the bug with the above gist and made sure it was fixed after applying this diff.

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
