Add option for controling app image class initialization

The new option is --initialize-app-image-classes. This attempts to
initialize app image classes by running the class initializers ahead
of time.

Will test this through test 660, but there are currently aborts when
it's enabled.

Test: test-art-host
Bug: 70735003
