Bug 854796: Anchor, area elements without href shouldn't have link role, r=Jamie,devtools-reviewers

Per the HTML-AAM spec, a and area elements without href attributes should have
generic roles. This revision implements this preference by creating hypertext
accessibles when said elements lack href attributes (or click listeners). A
byproduct of this change is recognizing that a elements have no intrinsic role
mapping; they could be generics or links. This revision handles situations
where href or click listeners might appear or dissapear, and recreates the
accessibles when necessary. Since image map areas are handled by their
containing image maps, this revision specializes HTMLAreaAccessible::NativeRole
to account for the discrepancy that we can't account for in the markup map.
This revision also changes the relevant WPT test expectations, updates existing
tests that this change affects, and adds tests to verify that changing href
and click listeners dynamically changes the role appropriately.
