Project Leyden added support to cache the AdapterHandleEntries in the AOTCache and to restore them from the cache rather than regenerating them.

Valhalla added a new `_sig_cc` field - a growable array of SigEntries - to the adapters. This field is currently nulled out in the ::remove_unshareable_info method.

We should update the adapter caching to also store the `_sig_cc` field into the AOTCache so we don't have to regenerate the scalarized calling convention info at runtime.
