Allow Thymeleaf to check for allowed method access of Java supertypes

To prevent Thymeleaf templates from accessing methods on built-in Java types that are not allowed, it ships with a list of allowed supertypes. Its org.thymeleaf.util.ExpressionUtils type has an isMemberAllowed method that calls getDeclaredMethods() on those types, so that needs to work for all these types in a native image. Recent versions of Thymeleaf have expanded the list with two additional types, which is why the M2 version has 7 new entries while the RC1 / latest has 9.
