Invalidate the object when aria-haspopup changes.

Explanation:

The cached native_role_ value, which is computed from
NativeAccessibilityRoleIgnoringAria(), must not return a different
result depending on whether aria-haspopup changes before/after the
caching.

This affects CanHaveChildren() for a button that changes its
aria-haspopup value. This in turn affects many other things for the
button, such such as aria-activedescendant computation.
