Fix hermes executor not available when use_frameworks is enabled (#34222)

Summary:
When in `use_frameworks!` + `hermes_enabled` mode, the React podspecs have not dependency to the `React-hermes` podspec. the `HermesExecutorFactory.h` is not available [here](https://github.com/facebook/react-native/blob/1d997ce6d67242b9f667b01365c5e719c3d3f8d7/React/AppSetup/RCTAppSetupUtils.h#L15) and [here](https://github.com/facebook/react-native/blob/1d997ce6d67242b9f667b01365c5e719c3d3f8d7/React/CxxBridge/RCTCxxBridge.mm#L44). The app will fallback to JSCRuntime and crash in release build because the JSCRuntime cannot evaluate Hermes bundles.

The pr tries to add `React-hermes` to Framework Search Paths and make the `HermesExecutorFactory.h` reachable when in use_frameworks mode.

This pr should fix the problem mentioned in [0.70 release discussion](reactwg/react-native-releases#26 (reply in thread)).

## Changelog

[iOS] [Fixed] - Fix Hermes executor not available when `use_frameworks` is enabled

Pull Request resolved: #34222

Test Plan:
use patch-package to apply the change to a RN 0.69.1 project with the following test cases:

- old architecture + jsc
- new architecture + hermes
- old architecture + `use_frameworks! :linkage => :static` + hermes
- old architecture +`use_frameworks! :linkage => :static` + hermes + release build
