Summary: Fixes Xcode release builds when Hermes is enabled. The Hermes debugger is loaded by the Hermes executor only if HERMES_ENABLE_DEBUGGER is defined. The hermes-engine Pod would set `HERMES_ENABLE_DEBUGGER=0` in release builds, but of course this would satisfy the HERMES_ENABLE_DEBUGGER ifdef check, leading to build time issues due to missing `hermes::debugger` symbols. Now, both the `hermes-engine` and `React-hermes` pods only set `HERMES_ENABLE_DEBUGGER=1` in debug builds. No gcc preprocessor definition is added by these pods in release builds.
