Remove LCP mouseover heuristic code.
This code was added as an experiment to disable late LCP entries
caused by a mouseover-to-zoom interaction, but doesn't reliably
prevent LCP in many cases.
Future work will replace this with a heuristic based on attributing new
LCP candidates to JavaScript tasks which can be traced back to a mouse
event listener. In the meantime, removing this code will allow the
existing code to be refactored and simplified.
