Hermes: Include iOS debug symbols in Hermes XCFramework

Summary:
Include dSYMs when building the universal XCFramework for Hermes iOS.

CocoaPods should pick up dSYMs automatically when using `vendored_framework` if:
- `hermes.framework` has a `hermes.framework.dSYM` in the same base directory
- `hermes.xcframework` has a `dSYMs` folder with a `hermes.framework.dSYM` in it, for each slice

The dSYMs for the macOS hermes.framework are already being created.
