Revert^4 "Walk internal ArtField/ArtMethod pointers"

Several of the new tests make use of the invoke-custom opcode. This
opcode is not supported by dexter/slicer causing the tests to fail.

This reverts commit c34eab45161c51bf63e548e44645cbcc59d01268.

Reason for revert: Added tests to redefine-stress known failures
Test: ./test.py --host --redefine-stress
Bug: 134162467
