RFR 8251414: Add test that invokeinterface of a protected method in java.lang.Object throws NoSuchMethodError

[Harold Seigel]

Hi,

Please review this change to add test cases to test 
hotspot/jtreg/runtime/8026394/InterfaceObjectTest.java to check for 
NoSuchMethodError exceptions when calling Object protected methods 
clone() and finalize() using invokeinterface.

The fix was tested by running the modified test on multiple platforms, 
including Mac OS, Windows, and Linux.

Thanks, Harold
