ngtsc has a robust suite of testing utilities, designed for in-memory testing of a TypeScript compiler. Previously these utilities lived in the `test` directory for the compiler-cli package. This commit moves those utilities to an `ngtsc/testing` package, enabling them to be depended on separately and opening the door for using them from the upcoming language server testing infrastructure. As part of this refactoring, the `fake_core` package (a lightweight API replacement for @angular/core) is expanded to include functionality needed for Language Service test use cases.
