RFR: 8368095: [leyden] Fix klass dependency recording [v2]

[Aleksey Shipilev]

> See the bug for symptoms. https://github.com/openjdk/leyden/commit/7b7648a4c9f67be509c6fccbcbc0502648388fdc exposed that our dependency recording is not actually accurate. Now that we check that precompiled tasks have dependencies recorded, before we treat class IK as fully initialized, _missing dependencies_ lead to premature replacement of AP4 -> A4, and potential trap from A4.
> 
> I see there are two missing things:
>  1. We want to record dependencies on object klasses as well, not only on plain metadata.
>  2. We want to record dependencies even when `cik->is_initialized()` returns `false` at the moment.
> 
> Additional testing:
>  - [x] Linux x86_64 server fastdebug, `runtime/cds`
>  - [ ] Benchmarks
