[Issue 16993] Documentation for toSimpleString and toString does not explain how they differ

--- Comment #2 from Jonathan M Davis <issues.dlang at jmdavisProg.com> ---
toString does currently call toSimpleString, but the intention is that if you
actually care about the format of the string, you don't use toString. Instead,
you use a function like toSimpleString or toISOExtString that's explicit about
the format. toString is just intended to convert the type to a user-friendly
string, not for specific formatting.
