[ICS02] Examine removing dyn ValidationContext type from check_header_and_update_state() and check_misbehaviour_and_update_state()

[Farhad-Shabani]

Summary

Part of #25

Examine the possibility of moving away from passing dyn ValidationContext type at check_header_and_update_state() and check_misbehaviour_and_update_state()

Description

This requires us to pass a Sized object and restricts us from exploring more generic ideas (Like incorporating associated or generic types within ValidtionContext / Module / Router traits or using blanket implementation to get the needed interface available for objects that implement ClientState/ Module traits)
As well, it does not seem efficient to pass all the context while needed data comes in via one or two methods.
