utils: ipc: Do not duplicate signals in proxy object

The specific proxy type (see `module_ipa_proxy.h.tmpl`) inherits `IPAProxy`,
the specific interface type, and `Object`. The interface type already
provides public definitions of the necessary `Signal<>` objects (see
`module_ipa_interface.h.tmpl`), so do not duplicate them.
