Fixed NodeRef not being implicitly cloned with components

[wdcocq]

Description

Passing a &NodeRef to a html component ref attribute would throw an error whereas with a html element it wouldn't.
A html component didn't use IntoPropValue on the ref attribute and thus didn't use ImplicitClone.

I've made
packages/yew-macro/src/html_tree/html_component.rs
more inline with how the ref and key attributes are implemented in
packages/yew-macro/src/html_tree/html_element.rs
To make subtle differences between the implementations clearer (e.g. notice the missing optimize_literals() on the key value before)

As discussed with @WorldSEnder on discord, I've moved the code to SpecialProps so it can be reused

This has tests, does what it advertises and cleans up inconsistencies (even removing lines overall). Looks good to me 🎉

Looks good to me. Until #2505 is resolved, this is a nice improvement
