8f283b93ea YGNodeComputeFlexBasisForChildren: remove output param
Summary:
@public

`YGNodeComputeFlexBasisForChildren` was using an output parameter (`float&`) that is always initialised to `0.0f`.
Here, we move the initialisation inside `YGNodeComputeFlexBasisForChildren`, and simply return the result.

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.

Currently only parent can tell the layout to align its children based on baseline. But if one of the children is a column or row then basealign does not work as expected.

We have added an api setReferenceBaseline which when set to true would mean that it's baseline would be considered as the reference baseline for parent amongst its siblings. If there are more than one siblings with referenceBaseline set, the first one would be considered.

8826d8b233 Allow CxxModules to implement methods with two callbacks (#21586)
Summary:
When writing a native module in C++ using CxxModule, its not currently possible to write async methods which take two callbacks, that shouldn't be projected to JS as a promise.  I hit this when trying to implement the AppState module in c++.  AppState has a single method on it, getCurrentAppState, which takes two callbacks (a success and a failure callback).

This change adds a couple of new CxxModule::Method ctors, which allow devs to specify that they want two callbacks, but not a promise.  This is done using an extra tag in the ctor, similar to how you specify that you want to make a synchronous method.  I used the existing AsyncTag to indicate that the 2 callback version should be async, and not a promise.

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).

Summary: React bytecode is kind of a different thing that sebmarkbage already has in mind so lets keep the namespace separate.

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
updateLayoutMountItem for reactTag: 420022 x: 0, y: 690, width: 454, height: 454
updateLayoutMountItem for reactTag: 420024 x: 454, y: 690, width: 455, height: 454
updateLayoutMountItem for reactTag: 420028 x: 0, y: 1171, width: 454, height: 454
updateLayoutMountItem for reactTag: 420030 x: 454, y: 1171, width: 455, height: 454
updateLayoutMountItem for reactTag: 420032 x: 0, y: 1651, width: 0, height: 0
```

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.
