[css-pseudo] Unify the default styles for ::marker

This patch avoids triplicating the default styles for the ::marker
pseudo-element in StyleResolver, LayoutListMarker and LayoutNGListItem.
Now they will only be in StyleResolver.

When no style has been specified for ::marker, using StyleResolver has
some overhead that reduces the the flexbox_with_list_item.html perf test
by 2%-5%. But unifying the code for ::marker styles seems worth it,
since it will be necessary to avoid some inconsistences like the
propagation of text decorations.
