interop: String/valueOf static + String is a CharSequence

Two interop gaps surfaced bringing up hiccup and malli:
- String/valueOf(Object): hiccup's compiler stringifies attribute values with
  (String/valueOf (or arg "")). Added the static — "null" for nil, else core-str.
- (instance? CharSequence s) returned false for a string; String implements
  CharSequence, and malli's :re validator gates on it before matching, so :re
  schemas always failed. instance-check now answers true for strings.
