Description

The existing API (SyntaxFactory.ParseArgumentList) only covers the new behavior for argument lists in invocations. But it doesn't expose options for parsing in context of attribute list (non-trailing named arguments disallowed) or with ranged arguments.

Relates to https://github.com/dotnet/roslyn/pull/20182#pullrequestreview-46136872

Contributor guide

Research direction
Review the related PR #20182 to understand the existing API and the discussion about non trailing named arguments. Then investigate how to extend SyntaxFactory.ParseArgumentList to support attribute lists and ranged arguments.
