proto: Remove deprecated `PackObjectsHook()` RPCpks-remove-pack-objects-hook

The `PackObjectsHook()` RPC is deprecated and its implementation has
been removed in 473e3540f (Deprecate PackObjectsHook, 2021-10-25).
Now that v15.0 is close, let's also remove the Protobuf definitions.

Changelog: removed
