Properly measure usage for Node attributes removed from DOM4

Properly measure usage for Node attributes removed from DOM4

The following Node attributes were removed from DOM4:
- namespaceURI
- localName
- prefix

However, those attributes were moved to Element and Attr in DOM4.
Therefore, we only want to measure usage of those attributes for other
types than Element and Attr to minimize the noise.

To address this issue, corresponding attributes were added to Element
and Attr interfaces so that those are used in priority for Elements
and Attribute nodes, and not the corresponding Node bindings code
whose usage is being measured.

Is this OK?

Otherwise, we should get rid of the MeasureAs since there will be too much
noise.
