Web Inspector: Audit: provide a way to get related Accessibility nodes for a given node

[Devin Rousso]

This corresponds to the following `DOM.AccessibilityProperties` properties (except they'd return `Node`s instead of `DOM.NodeId`s):
 - activeDescendantNodeId
 - childNodeIds
 - controlledNodeIds
 - flowedNodeIds
 - mouseEventNodeId
 - ownedNodeIds
 - parentNodeId
 - selectedChildNodeIds

Nit: Is this if check necessary, would elementsFromAttribute return a null element?

Nit: Is this if check necessary, would elementsFromAttribute return a null element?

> +    return nullptr;

Style: Sometimes you don't have a newline before the final return and sometimes you do. Would be nice to be consistent. I'd vote for always having a newline after a closing brace before a final return.

Nit: Is this if check necessary, would elementsFromAttribute return a null element?

It doesn't look like it, as `elementsFromAttribute` does its own check, but I think this isn't a bad thing to have.

We should never have to write code like:

    if (auto* x : list) {
        if (x)
            ...;
    }

Lets drop them. The originating code in DOMAgent doesn't have these checks.
