  [LFC][IFC] Figure out the logicalTopForNextLine without passing in the initial line rect
https://bugs.webkit.org/show_bug.cgi?id=246416

Reviewed by Antti Koivisto.

This is in preparation for using 0px as the initial line height to find correct vertical position for inline content when float boxes are vertically stacked within the line.
This patch preserves the current behavior where we move the line down by the computed line height to probe for floats.
