RFR: 8335159: Move method reference to lambda desugaring before Lower [v4]

[Maurizio Cimadamore]

> As we recently [moved](https://github.com/openjdk/jdk/pull/19836) the translation of "simple" method references from `LambdaToMethod` to `Lower`, it became clearer that this step in fact would benefit from running even *earlier*, as it depends on the synthetic casts generated by `TransTypes` (e.g. if one or more desugared lambda parameters have a type that is either an intersection or a union type).
> Moving the translation earlier would allow us not to *guess* which casts would need to be introduced, and just running `TransTypes::translate` on the desugaring code would take into account the type mismatches.
