This can lead to latent type errors for API users, because a swiftmodule would otherwise be emitted, without any diagnostics, containing imported decl with two global actor annotations on it. Such decls will always be an error to the typechecker when its eventually encountered. This patch drops all `@MainActor` annotations after the first one in the ClangImporter, regardless of whether its the safe or unsafe version, and emits a warning when doing so.
