[LayoutNG] Don't force legacy layout on ::first-letter pseudos.

Due to the complicated behavior of ::first-letter elements, where the
placement of the ::first-letter DOM node in the DOM tree doesn't
correspond with where we place the LayoutObject in the layout tree, it's
tricky to figure out whether it's part of a subtree that requires us to
force legacy layout or not. So just skip checking. The ::first-letter
element itself can never force legacy layout on its own, so we'll just
do whatever the parent layout object does.

Solution developed together with futhark@chromium.org
