Internals: Don't wrap elaboration severity task in an AstInitial (#6280) (#8142) 

An elaboration severity system task ($info/$warning/$error/$fatal used
as a module/generate/program/checker item), which is a module item,was
parsed as an AstInitial wrapping an AstElabDisplay. That put
AstElabDisplay (a non-statement) into the procedural statement list of
an AstInitial.

AstElabDisplay is evaluated by V3Width, which then deletes it. The
AstInitial wrapper is historic and has no effect.
