Summary Cease to exclude Swift message receiver source files

Certain features in WebKit generate Swift source code files for handling IPC messages in Swift. At the moment this is just some test code, but more will come along in future. It's currently necessary to exclude such files using EXCLUDED_SOURCE_FILE_NAMES in .xcconfigs, which is awkward for adoption of Swift message receivers, especially when they may be conditionally enabled. Rejig things so that this is no longer needed. We now know how to do this because the root cause problem was https://github.com/swiftlang/swift/pull/74415, causing Swift sometimes to interpret things within #if compiler blocks.
