[6.2] CMake: make the libswiftCompatibilitySpan symlink relative symlink (#84201) - **Explanation**: create the symlink from libswiftCompatibilitySpan.dylib to libswiftCore.dylib in the Swift build folder as a relative one instead of an absolute one, to support device testing. - **Scope**: CMake code that creates the symlink for libswiftCompatibilitySpan.dylib during builds - **Issues**: rdar://159314722 - **Original PRs**: #84200 - **Risk**: Low, scope is limited to configurations that run tests on a machine different form the builder, regular CI tests are not affected (since symlinks are valid on the builder itself), and packaging regenerates the symlink with a different mechanism. - **Testing**: ensured at desk that `stdlib/Span` test can run on a different machine (i.e. using `remote-run`) - **Reviewers**: waiting for reviews in the main PR
