Defines the target(s) a ConstraintValidator can validate. 
 A ConstraintValidator can target the (returned) element annotated by the constraint, the array of parameters of a method or constructor (aka cross-parameter) or both. 
 If @SupportedValidationTarget is not present, the ConstraintValidator targets the (returned) element annotated by the constraint. 
 A ConstraintValidator targeting cross-parameter must accept Object[] (or Object) as the type of object it validates.
