SwiftPM Regression: Binary Artifact Resolution in C++ Targets (#8056)

To reproduce

Note

This does not apply to the SwiftPM release, this regression only exists in the main branch of SwiftPM.

git clone git@github.com:wabiverse/SwiftPMBinaryTargetRegression.git
cd SwiftPMBinaryTargetRegression

swift build

If you comment out #1 and #2, swift build...and toggle them back in...swift build, you can reproduce this issue. I've tested against this PR, and it appears it fixes binary targets to be resolved from C++ targets.
