1. Support ? as wildcard marker under -Xsource:3 …

   Like in Scala 3.0, this allows `?` to be used as a type argument in all
   situations where `_` could be used as a wildcard previously. This should
   allow us to deprecate the use of `_` as a wildcard in Scala 3 to be able
   to eventually repurpose it as explained in
   http://dotty.epfl.ch/docs/reference/changed-features/wildcards.html
   
   This is a source-breaking change since a type named `?` is legal in
   Scala 2 (but not in Scala 3 unless -source 3.0-migration is used).
   `?` also has a special meaning when the kind-projector plugin is used,
   but that usage has been deprecated in favor of `*` for a while now.
