Resolve system SDK path via xcrun in explicit-modules scan - #1902

Conversation
The scanner assumed an unversioned SDK symlink (e.g. MacOSX.sdk) exists under each platform's SDKs directory. That symlink is not guaranteed to be present in every Xcode layout, causing scanning to fail with FileNotFoundError. Ask xcrun for the resolved SDK path instead, failing loudly if it cannot be determined.
