LibWeb+WebContent: Do not embed attributes as data in the Inspector HTML

Browse source 
Attribute values may contain HTML, and may contain invalid HTML at that.
If the latter occurs, let's not generate invalid Inspector HTML when we
embed the attribute values as data attributes. Instead, cache the values
in the InspectorClient, and embed just a lookup index into the HTML.

This also nicely reduces the size of the generated HTML. The Inspector
on https://github.com/SerenityOS/serenity reduces from 2.3MB to 1.9MB
(about 318KB, or 13.8%).
