`%target-embedded-link` now bundles `libswiftCore.a` (and `libswiftEmbeddedPlatformPOSIX.a` when available), so RUN lines that spell out `%target-embedded-posix-shim` or `%embedded-stdlib` alongside it are redundant. Also switch `concurrency-dynamic-isolation-link.swift` from raw `%target-clang` to `%target-embedded-link` so it picks up the stdlib archive through the same substitution.
