Summary: Previously we had a single `commit` function that accepts an argument that enables auto-retry mechanism. As Spencer pointed out, that wasn't so useful and clear. So, I split the method into two with more expressive names.

Summary:
I read my code and one thing stroke me: What if the same event emitter dispatches several events during the same event beat? In the previous implementation, only the first one will be delivered because the first `release` call consumes stored strong reference.
So, I changed the API a bit to make this more explicit: we have `retain` & `release` methods and we have a getter that works (multiple times) only if the object was successfully retained.

Summary: This diff implements a new algorithm that effectively marks `EventEmitter`s enabled or disabled. The previous implementation relied on a list of mutation instructions whereas the new one analyzes the shadow trees. The mutations-based approach didn't work well because mutations describe `ShadowView`s whereas some `ShadowNode`s are simply not views (like VirtualText), but we have to enable/disable them anyway.

Summary:
EventTargetWrapper and EventTarget were merged into one class that controls an `instanceHandle` reference and extracting a strong reference to it.
This diff also decouples the operation of retaining a strong reference (with checking a `enabled` flag) from actual usage of this reference. This allows to wrap into a mutex only first part of this process and avoid possible deadlocks.

Summary:
For some time we have had a nit trick inside `EventEmitter`: When event emitter is disabled, we switch to store `EventTarget` as a weak pointer instead of complete deleting it. Given some unpredictability of JS GC, it gave us some time to restore the pointer in case if we increment the counter right after decrementing this. Apparently, we found that it doesn't always work (obviously, sigh...), so we implement the `enableCounter_` and left this feature as it is assuming that it can nice optimization that illuminates some unnecessary constraints.
But, apparently, it's actually harmful, assuming that `jsi::WeakObject` (that thing that we use to refer to actual JS target) actually has "unsafe unretained" (not "weak") semantic.
So, we have to remove this.
This change will be particularly important for coming diffs in the stack.

Summary:
Instead of the whole family of commit* and complete* methods, now we have one single `commit` method which performs pre- and post-commit operations and swap pointers in a thread-safe manner. The `commit` operation is also exposing `revision` number and allows perform multiple commit attempts.
`completeByReplacingShadowNode`, `measure` and `constraintLayout` are also going away to RootShadowNode class in the next commits.
Why?
* Nicer API;
* No more recursive_mutex, no more problems with thread jumps;
* All mutex locks are now leaf-locks, so no more deadlocks possible;
* Exposing `revision` should help with debugging races.

Summary:
After this diff D13403925 that got rid of `-ffast-math` we started to have a very odd behavior on Yoga when using release builds.
After digging a while we found that certain set of conditions on O2 and O3 optimization levels was causing Origami to set some `INFINITE` values on Yoga.
We found the root of the problem and fix it on Origami side. But I'm wondering if guarding agains `INFINITE` on Yoga side would be good too. Since now Yoga it's not using `-ffast-math` anymore, and I think infinite is not a a valid value anywhere on Yoga side, it seems to support the reason to guard against it.
I'm happy to abandon this diff if you guys think this is not a good solution.

Summary:
This diff fixes a race condition that was detected on "Marketplace You" production test for Android.
The race condition happens when the method ShadowTree::complete is executed concurrently from two threads (in this case this is called from Scheduller::constraintSurfaceLayout and Scheduler::uiManagerDidFinishTransaction), based on the order of execution this bug makes MountViewItems to be dispatched to the UI in the wrong order.
The root cause of the bug is in the method:
```
bool ShadowTree::complete(
const SharedRootShadowNode &oldRootShadowNode,
const UnsharedRootShadowNode &newRootShadowNode) const {
newRootShadowNode->layout();
newRootShadowNode->sealRecursive();
auto mutations =
calculateShadowViewMutations(*oldRootShadowNode, *newRootShadowNode);
if (!commit(oldRootShadowNode, newRootShadowNode, mutations)) {
return false;
}
emitLayoutEvents(mutations);
if (delegate_) {
delegate_->shadowTreeDidCommit(*this, mutations);
}
return true;
}
```
Notes:
- the commit method is guarded by the commitMutex_
- the shadowTreeDidCommit() method dispatches mutations instructions to the platform side.
- If there are two threads running concurrently, there is no guarantee that the shadowTreeDidCommit() is going to be called in the correct order.
The solution is to include the execution to shadowTreeDidCommit() in the same commitMutex_
Possible solutions:
1 - move the commitMutex_ out of the commit method (to the completeMethod)
2 - synchronize the call to complete method() - this is the implemented solution.
I chose this solution to make it consistent with the way Scheduler::constraintSurfaceLayout is implemented (https://fburl.com/8l49no5x)
This mechanism is very likely to change in the refactor of threading mechanism that Valentin Shergin is going to be working on January.
I would like to land this, so we can fix this bug and run another experiment in production as soon as possible.
