ART: Disable CHA for AoT

App images and boot image CHA do not interact well. If boot image
methods have been marked single-implementation, but lose that
status when compiling an app image, that information is not
retained, and after loading the image at runtime, the state will
be inconsistent. As a workaround, disable CHA during AoT.

Modify expectations of run-test 616-cha.
