60c711d4 - Sema: Fix a regression in retroactive conformance diagnostic suppression.

Sema: Fix a regression in retroactive conformance diagnostic suppression. Module qualifying a protocol name in an inheritance clause should suppress retroactive conformance diagnostics for the protocol and any protocols it inherits from, just like adding the `@retroactive` attribute. Fixes a regression in Swift 6.2 introduced by https://github.com/swiftlang/swift/pull/81576. Resolves rdar://162295268 and https://github.com/swiftlang/swift/issues/85153.
