Use RN Build Utils for Building Hermes Artifacts

Summary:
We moved Hermes some build utils from [Hermes repo](https://github.com/facebook/hermes/tree/main/utils) to [React Navtie repo](https://github.com/facebook/react-native/tree/main/sdks/hermes-engine/utils) a while ago to have more control over them. However some paths on the CI were not updated. We continued to use old build scripts for Hermes prebuilds. Some unfortunate side effects are:
- `HERMES_ENABLE_DEBUGGER` is [hardcoded to true](https://github.com/facebook/hermes/blob/main/utils/build-apple-framework.sh#L65). That makes Hermes much slower in Release configuration.
- BUILD_TYPE is [set to Release](https://github.com/facebook/hermes/blob/main/utils/build-apple-framework.sh#L10) instead of `MinSizeRel` which inreases Hermes binary size.

This diff copies these build utils from RN to Hermes source directory before we perform Hermes build.
