## Changelog:
[Internal] [Fixed] - keep track of last direct manipulation props
* so that at next time there's a ShadowTree commit (regardless of which thread), they're merged into the update mutation
* the props will stay until the view is disconnected from props node via Animated API or the view is removed/deleted. This should be expected behavior, because in RN we expect that once Animated changes a prop, subsequent react commits should not change the value.

Pull Request resolved: https://github.com/facebook/react-native/pull/52813
Changelog: [General][Changed] CDP backend now accepts addBinding and removeBinding methods earlier, before a Runtime exists.
Allows managing CDP binding subscriptions at any point in time, including at the very beginning of a session when a `RuntimeAgent` doesn't yet exist (due to `registerRuntime` not having been called yet).
"Adding" a binding with the `Runtime.addBinding` method is actually two actions in one:
1. Subscribing the current session to events from a particular binding name, from one or more Runtime(s) that may exist now or in the future (optionally targetable by execution context ID/name).
2. Installing a JSI function with the given `name` on the global object of the targeted Runtime(s), if they exist at the time of the method call.
NOTE: "Removing" a binding only involves managing the subscription and never causes the corresponding JSI function to be uninstalled - presumably because it may have been captured by user code anyway.
We currently do both (1) and (2) in `RuntimeAgent`, but this means subscriptions can't be managed before a `RuntimeTarget` has been created, which can cause problems if we want to set up certain bindings programmatically during React Native's initialisation. As this is an unnecessary restriction, here we move (1) to `HostAgent` and keep only (2) in `RuntimeAgent`.

This diff makes the Yoga/Yoga.h header an umbrella header, which means that it includes all of Yoga's public headers. The code changes in each file include adding the IWYU pragma export to each header file, which is a way to tell the compiler to export the header file's symbols to other files that include it. This is necessary for the header file to be used as an umbrella header.

Summary:
Hello, I work on [Radon IDE](ide.swmansion.com) I encountered an issue while adding support for react native 81, this PR solves it:
In https://github.com/facebook/react-native/issues/51023 EvanBacon removed `displayName` filed from `View` component adding the following comment:
>Remove displayName in favor of component name. I'm not 100% sure this is a full fallback but it is valid according to react/display-name eslint rule—https://github.com/jsx-eslint/eslint-plugin-react/blob/master/docs/rules/display-name.md
Unfortunately the Fabric renderer uses the `displayName` property to generate the name of the component for the inspector functionality and in absence of it generates a name that might be confusing to the end user:

Problem is not specific to Radon and happens in chrome devtools as well:

This PR brings back the `displayName` property to fix that.

1. Fix forward from D76486572 (cc christophpurrer) - `#include <format>` is, for whatever reason, not available in fbcode (?) but `fmt` is an adequate, working substitute that is also used elsewhere RN (specifically in ReactCxxPlatform). Also removed the `folly/Format` include that had erroneously been left in, and the `fbobjc_ios_propagated_target_sdk_version` setting that was added purely to support `<format>`.
2. Fixes a dangling reference to an immediately-destroyed `MockHostTargetDelegate` in `ReactInstanceIntegrationTest`, caught by ASAN.
3. Adds a missing `#include <stdexcept>` to `Utf8.h`.
