Subject: [PATCH] [autolink-extract] Update deduplication list for new
 Foundation, Testing, and WASI platform

We now have several new runtime libraries in the toolchain but they are
not listed in the autolink deduplication list. This can lead to an excessive
memory footprint when linking on platforms that use autolink-extract.

See https://github.com/swiftlang/swift/issues/58380
