When `__attribute__((swift_attr(“@Sendable”)))` is applied to a clang parameter Swift now attempts to make the type `Sendable` in a more comprehensive way than before: * If it is a function type, it adds `@Sendable` to it. * If it is a protocol composition type, it adds `& Sendable` to it. * If it is a class, protocol, or generic class, it inserts it into a protocol composition and adds `& Sendable`. * If it is a typealias, it *may* desugar it to a modified version of the underlying type. * In various other cases, it recurses into the children of the type. This allows Objective-C methods and functions to require that their arguments have a Sendable type without specifying a particular type they must belong to. Fixes rdar://87727549.
