free function serialization DSL 

Example usage for Seraphis types (in global or `sp` namespace):

```
BEGIN_SERIALIZE_OBJECT_FN(sp::SpCoinbaseEnoteCore)
    FIELD_F(onetime_address)
    VARINT_FIELD_F(amount)
END_SERIALIZE()

BEGIN_SERIALIZE_OBJECT_FN(sp::SpEnoteCore)
    FIELD_F(onetime_address)
    FIELD_F(amount_commitment)
END_SERIALIZE()
```
