When compiling for visionOS, iOS availability attributes are remapped into the visionOS availability domain automatically. While the version remapping was being performed correctly, there was a regression that caused the platform name to be printed incorrectly in many diagnostics. Whenever an iOS version is remapped to a visionOS version, availability diagnostics will now present those versions as visionOS versions instead of iOS versions. Resolves rdar://146293165.
