IRGen: Try harder not to emit calls to swift_getExtendedExistentialTypeMetadata()
This entry point doesn't exist on older runtimes. Sema enforces that constrained existentials don't appear in substitution maps, however IRGen would sometimes try to instantiate metadata even if the user didn't do that. Fixes #64657.
