Should isDataClassEqualTo used internally in isEqualTo

[emartynov]

This is tedious to remember different method for data class.
As well implementation could check if it is data class and just go to more extended check.

Via reflection (KClass.isData)? I'd be interested in the rationale behind this not being the initial approach, too

isDataClassEqualTo probably shouldn't even be public API. Enhancing isEqualTo for JVM-only data class users is probably okay. Although it could still mislead as all properties might compare equal in spite of the class equality failing.
