Please update the comment in `aotArtifactFinder.hpp` to mention the annotation;
it currently mentions the C++ accessor but should also mention the annotation
that drives it.
A class is AOT-init if EITHER it has the `@AOTClInit` annotation OR it is in
the heap for other reasons. So it’s harmless to put `@AOTClInit` on those
extra classes that need `runtimeSetup` calls.
If you agree with that logic, then I recommend not having a separate `@RTS`
anno as well. I don’t think that second anno pulls its weight. Just execute
the `runtimeSetup` method in any annotated class, as part of the contract of
that annotation.
In the future we may also want an `assemblyCleanup` hook in the same potential
places.

this name needs to be adjusted in the comments
