Build JSI, React-Debug, React-logger, React-MapBuffer with SPM (#50075)

Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/50075 This is an exploratory change to see how it will look like to build core from SPM. In this change we are building three pieces of React native (using the Podspec names for simplicity): - React-jsi - React-debug - React-logger - React-MapBuffer They depends on a local ReactNativeDependency.xcframework we can build using the prebuild-io script. ## CHANGELOG: [INTERNAL] - set up initial Swift PM configuration Reviewed By: cortinico Differential Revision: D70567840 fbshipit-source-id: 3f65a3e7c3dd39f71f6d4c04726712a5968e0a97
