Configure Package.swift file to be able to build from source (#53667)

Summary:
Pull Request resolved: #53667

This change updates the Package.swift file to enable building RNTester and HelloWorld from source.

The set of changes is the following:
- add a BUILD_FROM_SOURCE flag to toggle between building for creating prebuilds and building an app from source
- configure the proper header search path based on whether we want to build an app from source or not
- split the ReactFabricComponents target in multiple subtargets. This is required because when building from source we can't have targets whose Source folder is overlapping.
