Fix symbol not found _jump_fcontext with use_frameworks! (#42230)
Summary:
Pull Request resolved: #42230
While developing Xcode 15, Apple reimplemented the linker.
In Xcode 15.0, the linker was making old iOS (< 15) crash when they were built using Xcode 15.
To fix that, we make Apple create new compiler flags (`-ld_classic`) to have a backward compatible linker.
In Xcode 15.1, Apple fixed that behavior, so the flags should not be required anymore.
But now, if we pass `-ld_classic` to the linker and we have an app that is using `use_framworks!`, that app crashes at startup.
This change remove the flags if the Xcode that is used is 15.1 or greater.
*Note:* The previous change added the flags to Hermes as well. I tested this fix in a configuration where Hermes has the flags and React Native does not, and it works. So we are removing the flags only from React Native.
This Fixes#39945
## Changelog:
[Internal] - Do not add the `-ld_classic` flag if the app is built with Xcode 15.1 or greater.
