This reverts most of #17740 and instead add a check on currying in SAMType. We could consider allowing curried methods in SAM types, but this would be a language change that requires a SIP, and the implementation would need an adaptation step in erasure since the invokedynamic method needs to have a compatible signature with the abstract method in the trait.
