Currently all of our migrations are set up to find the tsconfig paths within a project, create a `Program` out of each and migrate the files inside of the `Program`. The problem is that the `Program` can include files outside of the project and the CLI APIs that we use to interact with the file system assume that all files are within the project. These changes consolidate the logic, that determines whether a file can be migrated, in a single place and add an extra check to exclude files outside of the root. Fixes #39778. PR Close #39790
