swift-package-manager: Build tool plugins don't work on Windows

Description

This PR on a minimal project demonstrates. You can see that builds succeed everywhere but Windows.

This is after I’ve worked around the SPM Path bugs. It complains that it can’t find the executable used by the build tool. Various attempts to fix it by adding .exe to the path are in the preceding commits on the same branch; none of them worked.

Expected behavior

Project works on Windows just like on Mac and Linux.

Actual behavior

No response

Steps to reproduce

As shown above I’m seeing the duplicate main symbol when linking a test runner that indirectly depends on a macro. I comprehend that macros != plugins but they share the trait that they compile to separate executables not intended to be linked into the test runner. I’ll aim to create a reproducible test repo as soon as possible.
