Allan Shortlidge d3dbe75419 ModuleInterface: Introduce the %target-swift-emit-module-interface and %target-swift-typecheck-module-from-interface lit substitutions and adopt them in some tests that involve emitting a swiftinterface. The substitutions specify the additional flags -swift-version 5 -enable-library-evolution. There are a few motivations for adding these substitutions: ...

- Tests that depend on emitted interfaces should generally use flags that are typical for modules that have textual interfaces (e.g. `-enable-library-evolution`).
- If a test is intended to produce a valid `swiftinterface` then it should verify that interface. This will help prevent interface printing regressions caused by compiler changes.
- Having commonly used substitutions for tests that emit interfaces makes it easy to experiment with compiler flags that might effect interface printing.
