Hygiene: Remove link element from LINK_ABANDON_*

Browse source 
Initially, the link element was added to LINK_ABANDON_* to determine
when an interaction should be reset. However, this wasn't enough to
protect against timing-related bugs, e.g. T154923. Now that tokens are
used to determine when interactions should be reset, the link element
can safely be removed from the LINK_ABANON_* actions.

Supporting changes:
* Update the return type of mw.popups.actions.linkAbandon in its
  DocBlock.
