[jdk20] RFR: 8299891: JMX ObjectInputFilter additional classes needed

[Kevin Walls]

The default setting for the ObjectInputFilter for JMX, introduced in jdk20, is too restrictive.
javax.management.Attribute and AttributeList classes are also needed, and Query related classes.

There are a number of Query-relate classes, so adding javax.management.* is appropriate otherwise the list becomes hard to manage.  This is a * and not a ** which would mean all subpackages, so the openmean subpackage stays in the list.
