Update dirty-image-objects file

Split dirty-image-objects file between ART and framework modules -
depending on where the classes are defined.
This will allow dirty-image-objects to stay relevant in case only one of
the modules is updated.
Add .txt extension to dirty-image-objects file.
Update AndroidRuntime to use new paths.

Bug: 346990440
Test: presubmit
Test: install ART jitzygote module, check that dex2oat receives new
paths to dirty-image-objects files
