[Gradle] Streamline how cinterop artifacts are exposed within a Gradle project

Before:
- The cinterop task's output files were added as file dependency
to the declaring target's apiElementsConfiguration
- A 'copy' task was created for the cinterop artifact that was added
to the apiElements configuration as artifact (and therefore also
to the apiElements-published). This copy task placed the
same klib into the 'libs' folder
- Before passing libraries to the compiler the, all files
that are likely to be the result of the 'copy' task (in any libs dir) were
filtered

After:
- The cinterop task's output files are *not* added as file dependency
- The cinterop task's output is added as artifact directly to
the 'apiElements' configuration
- There is no more need for a copy task
- There is no more need for manually filtering the 'libs' artifacts

Tested:
project to project dependencies,
project to project dependencies (with KGP based dependency resolution)
project to repository
project to repository (with KGP based dependency resolution)
