feat(vm): add `CommentGroup` and `Comment` attributes

[gfanton]

Add CommentGroup and Comment attribute support to the VM. The main reason behind this is to have the ability to handle special directives such as // nolint without having to re-parse every file. I've left some XXX comments in places where I'm unsure of what to do.
