The Swift service validateSerializedAST now accepts the name of the client SDK to limit loading only swiftmodules built with the same SDK. This prevents loading swiftmodules built with an incompatible SDK where the context is different enough that it can lead to hard compiler crashes. In this use site, loading the swiftmodule from a binary should be safe as the SDK context will be extracted from that swiftmodule. Other imports will use regular loading path and apply the expected restriction. Swift API change: swiftlang/swift#58935
