This commit introduces a new interface, which abstracts access
to the underlying `FileSystem`. There is initially one concrete
implementation, `NodeJsFileSystem`, which is simply wrapping the
`fs` library of NodeJs.
Going forward, we can provide a `MockFileSystem` for test, which
should allow us to stop using `mock-fs` for most of the unit tests.
We could also implement a `CachedFileSystem` that may improve the
performance of ngcc.

The `Transformer` and `Renderer` classes do not
actually need a `sourcePath` value as by the time
they are doing their work we are only working directly
with full absolute paths.

Previously, ngcc would insert new imports at the beginning of the file, for
convenience. This is problematic for imports that have side-effects, as the
side-effects imposed by such imports may affect the behavior of subsequent
imports.
This commit teaches ngcc to insert imports after any existing imports. Special
care has been taken to ensure inserted constants will still follow after the
inserted imports.

We have already removed this concept from the public API. This just cleans it out altogether.
The `targetPath` was an alternative output path to the original `basePath`.
This is not really a very useful concept, since the actual target path
of each output file is more complex and not consistently relative to the `basePath`.

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.

By ensuring that EntryPointBundle contains everything that `Transformer.transform()`
needs to do its work, we can simplify its signature.
