[cxx-interop] Disable test with an older runtime

848fad0 introduced support for printing foreign reference types. It changes both the compiler and the runtime, and having the runtime change applied is required for the test to pass. Let's not try to run it with an old runtime.

This change also splits up a test for printing of value types from a test for printing of foreign reference types, since we don't have any runtime restrictions for value types.
