Subject: [PATCH] refactor(@angular/build): provide private factory API for
 internal compilation infrastructure

The `createAngularCompilation` factory function is now available from the
`private` entry point for the `@angular/build` package. All items exposed
from this entry point are not subject to SemVer guarantees and may change between
releases.
