RFR: 8315128: jdk/jfr/event/runtime/TestResidentSetSizeEvent.java fails with "The size should be less than or equal to peak"

[Erik Gahlin]

Could I have a review of PR that makes sure _peak_ is always above or equal to _size_ for the resident size event.

Change was suggested by Stefan Karlsson. See bug for details.

Testing: 100 * jdk/jfr/event/runtime/TestResidentSetSizeEvent.java

Thanks
Erik
