757518edba Fabric: ShadowTreeRegistry::get was renamed to ShadowTreeRegistry::visit

dea8773c19 Fabric: ValueFactory and EventEmitter::dispatchEvent based on that
Summary:
Now the event delive pipeline supports `JSI::Value`-based payload. Instead of passing `folly::dynamic`, now we are passing `std::function<jsi::Value(jsi::Runtime &runtime)>` as factory that can build a `JSI::Value` with given `jsi::Runtime` and any captured data.
The old (now legacy) way of calling `EventEmitter::dispatchEvent(..., const folly::dynamic &payload, ...)` is also supported.

b4fa1fa0c6 Fabric: Introducing ShadowTreeRegistry
Summary:
Why do we need a dedicated registry class?
* We need to simplify registry-related logic in Scheduler.
* We need to couple threading aspect of the registry with the registry itself, otherwise it's not clear why exactly we acquire the mutex. We also should not acquire the mutex in a per-method way (as we did before), because it's incorrect and misleading (only lines that access the registry should by protected).
* We need to have a way to share the registry with other classes (e.g. UIManager) without passing a reference to the whole Scheduler.

18d8c48c01 Fabric: Introducing UIManagerBinding, a replacement for JSIFabricUIManager
Summary:
This diff changes how we expose UIManager to JavaScript realm and control ownership of it. This change should improve reliability and a thread-safety.

UIManagerBinding is a HostObject which consolidate ownership of UIManager. Now JavaScript's GC controls its lifetime which eliminates the possibility of calling some JS facing methods of UIManager using a dangling pointer.
Besides that, all API now imply that if the caller has a reference to jsi::Runtime, it calls the method on the proper thread (it's an implication of RuntimeExecutor design).

df4521e6c4 Fabric: Making jsi::Runtime a part of EventBeat and EventPipe
Summary:
We double down on JSI in Fabric. So, practically, JSI is now a hard dependency for Fabric. I hope it's for good.
Now `jsi::Runtime` is coupled with scheduling via `EventExecuter`, so we have to make `jsi::Runtime` a part of `EventBeat` to proxy runtime reference to bindgings.

7b5277bb75 mostly working on Android + OTA
Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:

Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```
updateLayoutMountItem for reactTag: 420006 x: -440, y: -13, width: 931, height: 78
updateLayoutMountItem for reactTag: 420010 x: 26, y: 79, width: 0, height: 1651
updateLayoutMountItem for reactTag: 420012 x: 0, y: 26, width: 0, height: 158
updateLayoutMountItem for reactTag: 420016 x: 0, y: 210, width: 454, height: 454
updateLayoutMountItem for reactTag: 420018 x: 454, y: 210, width: 455, height: 454

aab01608ba Update and expand bytecode spec
Summary:
* Adds parent tag as param for createNode in place of explicit appendChild commands.
* Adds version info to bytecode
* Adds native conditional support:

Conditionals are represented in product code with the new `NativeConditional` React
component. It takes params necessary to construct a native function call, and takes
a render prop as a child that passes the value of the native call as an arg. In
prod, the component would actually call the native module and render with that value,
but in jest we render for *both* true and false and set them as children
of a new jest-only primitive/host component which we special-case and generate a
special command with `OP_CODE.conditional`, generate the appropriate bytecode commands
for each branch, and embed them as args in the conditional OP_CODE command. When
evaluating the bytecode, only one set of commands is executed, based on the native
module value (which is evaluated with another new opcode which computes the value
and stuffs it in a "register").

Obviously generating this bytecode is kind of a cludge compared to prepack, but
when I asked @[501709947:Dominic] about it, he said they had no bytecode spec right
now, so I'm running ahead with this prototype. The main thing I'm focused on is
the C++/RN bytecode interpretter - this jest stuff is just a way to generate bytecode
for it to consume which could be replaced or augmented with many other approaches,
such as prepack, server rendering, etc.

Also piggybacked a bunch of other cleanup.

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

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`.

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.

This is also fit good to our policy where "everything is const (immutable) by default".
