Just a small quality of life improvement. It forces the test functions in benchmarks to have the name of the test case if it's an anonymous function, so it shows better in stack traces.

This is just an intermediate change to simplify how we format Fantom configs, so we can extend it to use other formatting formats (e.g.: short format to use in file names).

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.
## Changelog:
[INTERNAL] [FIXED] - Bring back the displayName property to the View component
Pull Request resolved: https://github.com/facebook/react-native/pull/52688
Test Plan:
- Run the application
- open chrome devtools and navigate to "components" tab
- before changes the View components would show up as `View_withRef` after they are named `View`

The handling of `Tracing.start` was needlessly split between `HostAgent` and `TracingAgent` because `TracingAgent` did not have a reference to the session state (which, being an Agent, it's allowed to have). This diff cleans that up.

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`.

EDITS: After backout, fixed the issue where we were incorrectly setting the `accessibility_order_parent` tag the ReactAxOrderHelper class instead of the actual view. Also, made the cast safe to prevent any unexpected issues.
Also refactored the ReactAxOrderHelper functions to not have the block scoped `traverse` functions in favor of just looping through the children of a view when calling them

Reported locations for errors in Fantom is wrong, because it seems it's not ignoring "infra" frames.
This was caused by the `stack` property in `ErrorWithCustomBlame` being set on the error objects and shadowing the getter that removes the necessary frames. This fixes that by forcing that property to be deleted.
