This patch adds an apinotes file for SwiftWASILibc clang module to mark `errno` macro hidden from Swift code. This resolves ambiguity between the C macro definition and the Swift wrapper in WASILibc overlay module. This change installs the apinotes file to the resource directories for both lib/swift/apinotes and lib/swift_static/apinotes.
