`HtmlElement::attrs` and `DynAttrs::dyn_attrs` Accept `&'static str` Instead of `Oco<'static, str>` about leptos

I don't think it's possible to change these function signatures in a way that isn't technically a breaking change, although I may be wrong. I do know that they will change significantly in the next release as part of the wider renderer rewrite, so I will mark this issue as 0.7 to make sure there's a decent solution then.

0.7 does support spreading arbitrary attributes of any kind onto any component, which seems to me like it should help.

Also, I don't see any reason why the Binding::Attribute name is &'static str instead of Oco<'static, str>. Because of this, I can't do the following:

use leptos::*;

#[component]
pub fn MyComponent(
    #[prop(attrs, optional)] attrs: Vec<(Oco<'static, str>, Attribute)>,
) -> impl IntoView {
    view! { <span {..attrs}></span> }
}
