misc: cleanup &Arc<dyn T> -> &dyn T

Browse Source 
Consuming `&Arc<T>` as argument is almost always an antipattern as it
hides whether the callee is going to take over (shared) ownership
(by .clone()) or not. Instead, it is better to consume `&dyn T` or
`Arc<dyn T>` to be more explicit. This commit cleans up the code.

The change is very mechanic and was very easy to implement across the
code base.
