feat(s3): add missing storage classes and API cleanups

Fixes #2708

BREAKING CHANGE: `s3.StorageClass` is now an enum-like class instead of a regular
enum. This means that you need to call `.value` in order to obtain it's value.
* **s3:** `s3.Coordinates` renamed to `s3.Location`
* **codepipeline:** `Artifact.s3Coordinates` renamed to `Artifact.s3Location`.
