SI-7848 Xlint no warn on $sym with params
This idea brought to you by retronym.
Also improve implicitNotFound detection at typer;
and avoid checking the standard interpolation
expression for cases like s"some $$x".
Some minor refactorings of implicitNotFound strings.
The intersobralator allows extra spaces, i.e., trims.
