astgen: generate type specific addNext, remove astNextNull

Browse Source 
Generate type specific static overloads of Ast<Node>::addNext, which
return the correct sub-type of the 'this' they were invoked on.

Also remove AstNode::addNextNull, which is now only used in the parser,
implement in verilog.y directly as a template function.
