Previously, simpleExpr was recovered as Literal(Constant(null)) which led to some errors in interactive.

Type inference in Scala 3 works on whole chain, thus type vars were inferred as union type of Null because of this very reason. Recovering such errors as unimplementedExpr which has a type of Nothing, solves the issue.

…nimplemented expr (#21438)

We should not emit more errors that came from our error recovery term
trees.

Previously, we've recovered those situations with unimplemented
expression term added in #19103
and before that it was just a `null`
