[lworld] RFR: 8326048: [lworld] LibraryCallKit::arraycopy_restore_alloc_state needs to handle _newNullRestrictedArray intrinsic

[Tobias Hartmann]

Follow-up from [JDK-8325106](https://bugs.openjdk.org/browse/JDK-8325106): We hit an assert because we create a wrong JVMState in `LibraryCallKit::arraycopy_restore_alloc_state` for re-executing the `newNullRestrictedArray` intrinsic because the code does not account for the class argument on stack in addition to the size.

I also fixed an independent issue with handling circularity.

Best regards,
Tobias
