### Motivation: Projects that use C++ interop for some of the Swift targets were failing to build in test mode (`swift test`) because the generated test entry point target wasn't being compiled with C++ interop enabled. ### Modifications: The logic that propagates the C++ interop compiler flag (`-cxx-interoperability-mode`) to the discovery target now also runs for the entry point target. rdar://125498997 (cherry picked from commit f529dae)

Explanation: Projects that use C++ interop for some of the Swift targets were failing to build in test mode (
swift test) because the generated test entry point target wasn't being compiled with C++ interop enabled.Scope: Flags that are being passed to the entry point test target.
Risk: Low, this only affects projects that explicitly enable C++ interop in the package manifest on non-Darwin platforms only.
Testing: Added a build plan test.
