Faster `HLoadClass` for app image classes.
Add app image relocations for classes in the app image,
similar to the existing relocations for boot image. This new
load kind lets the compiled code avoid the null check and
slow path.
Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing --speed-profile
Test: run-test.sh
Test: testrunner.py --target --optimizing --speed-profile
