When diagnosing a declaration that is more available than its context, to preserve source compatibility we need to downgrade the diagnostic to a warning when the outermost declaration is an extension. This logic regressed with swiftlang#77950 and my earlier attempt to fix this (swiftlang#78832) misidentified what had regressed. Really resolves rdar://143423070.
