#1319) This reverts commit 66c25e6. The `dst` output parameter could make it problematic for a higher-level language. Such output parameters typically result in unexpected allocs in C bindings from a managed language making the subsequent `call_perform` likely to fail. On the other hand, one can derive the value of the `dst` output parameter by computing the difference in canister cycles balance before and after calling `call_cycles_add128_up_to` (confirmed empirically) which might allow us to avoid the output parameter.

Introduces `call_cycles_add128_up_to` to the system API to offer a way of adding as many cycles as possible to a call without trapping in the subsequent `call_perform`.
