[DOC] Rewrite docs for rb_sym2str()

Browse Source 
Explaining this by reference to rb_id2str() obscures a few important
details because IDs and symbols don't map to each other perfectly (you
can have a dynamic symbol without an ID!) Also, it used to take 2
redirections to get to concrete information, and I think being more
direct is friendlier.
