feat(ivy): ngcc - support creating a new copy of the entry-point format (#29092)

Browse Source 
This commit adds a `NewEntryPointFileWriter` that will be used in
webpack integration. Instead of overwriting files in-place, this `FileWriter`
will make a copy of the TS program files and write the transformed files
there. It also updates the package.json with new properties that can be
used to access the new entry-point format.
