Replace assert_precondition with assert_implements in largest-contentful-paint/ (#23006) assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md). Since LargestContentfulPaint is not an OPTIONAL part of the Largest Contentful Paint spec, these tests should use assert_implements.
