Remove feature LCPMultipleUpdatesPerElement
This feature is to make the same element an LCP candidate again if it's
updated. It is added by this CL https://crrev.com/c/3924764. The
feature is never launched. We decided to remove it.
The CL that added this features seems only makes text layout objects
eligible for LCP by short-circuiting the already-seen check. Images
are not touched, although the commit msg seems to hint otherwise.
This CL removes the short-circuiting and modified the wpt.
