Revert "Revert "Ensure Proxy frames work with JVMTI stack frame functions""

This reverts commit d108d9ea.

It seems we have a bug somewhere in our proxy or stack-visitor code
causing StackVisitor::GetThisObject to return an object with a null
klass_. Added a temporary skip for the test configurations that expose
this until it can be fixed.

Bug: 66903662
Bug: 67679263

Reason for revert: Added skip for test that exposes a pre-existing bug
in our stack-visitor/proxy-object support.

Test: ./test.py --host -j40
Test: ./test/testrunner/testrunner.py --host --gcstress -t 1939
