Remove QJS exception API

This API has been deprecated for a while. It's legacy stuff from
QtScript.

Until someone proves that QJSValue::isError() isn't sufficient to
handle JavaScript exceptions, we won't provide any additional API
for that.

Also removed QJSValuePrivate::lessThan(), which was using the
exception mechanism, but the function itself wasn't used anymore
(another remnant from the QtScript days).
