protected def transformPhase(using Context): Phase

The phase in which the transformation should be run. By default this is the phase given by the this macro transformer, but it could be overridden to be the phase following that one.

Is this phase the standard typerphase? True for FrontEnd, but not for other first phases (such as FromTasty). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
