The `generate` RPC method:
- was introduced in 2010
- is now only used for testing
- reaches across multiple components (wallet, mining)

I propose we remove the wallet `generate` RPC method and update all tests to use the `generatetoaddress` RPC method. We can do this non-invasively in the test framework by adding a `generate` method to `TestNode` so that the individual tests do not need to be updated. We could also add a `generate` alias to the `generatetoaddress` RPC method.

Doing this removes a wallet->server dependency and simplifies the wallet->server interface (#10973).

I'm opening this issue before implementing in case anyone has objections.
if (it != pwallet->mapKeyMetadata.end()) {
            meta = &it->second;
        }
    }
    if (!meta) {
        auto it = pwallet->m_script_metadata.find(CScriptID(scriptPubKey));
        if (it != pwallet->m_script_metadata.end()) {
            meta = &it->second;
        }
    }
    if (meta) {
        ret.pushKV("timestamp", meta->nCreateTime);
        if (!meta->hdKeypath.empty()) {
            ret.pushKV("hdkeypath", meta->hdKeypath);
            ret.pushKV("hdseedid", meta->hd_seed_id.GetHex());
            ret.pushKV("hdmasterkeyid", meta->hd_seed_id.GetHex());
        }
    }
    
    
    
    UniValue labels(UniValue::VARR);
    std::map<CTxDestination, CAddressBookData>::iterator mi = pwallet->mapAddressBook.find(dest);
    if (mi != pwallet->mapAddressBook.end()) {
        labels.push_back(AddressBookDataToJSON(mi->second, true));
    }
    ret.pushKV("labels", std::move(labels));
    return ret;
}
