[Dependency Scanning] Pull optional dependencies from the adjacent binary module for direct interface dependencies

Browse Source 
For a `@Testable` import in program source, if a Swift interface dependency is discovered, and has an adjacent binary `.swiftmodule`, open up the module, and pull in its optional dependencies. If an optional dependency cannot be resolved on the filesystem, fail silently without raising a diagnostic.
