9cabfc26 - [CSSimplify] If function types mismatch on labels record a contextual mismatch

[CSSimplify] If function types mismatch on labels record a contextual mismatch `RelabelArguments` cannot possibly diagnose this issue because there are no argument lists in this case. Let's report contextual mismatch instead. Resolves: https://github.com/apple/swift/issues/59058 (cherry picked from commit 8fd8408075b2493293dc47a66fcadc0c08e6d039)
