Invalidate all non-composited descendants on fixed-position changes

Invalidate all non-composited descendants on fixed-position changes

This patch updates invalidateDisplayItemClientForNonCompositingDescendants
to use LayoutObject::invalidateDisplayItemClients(...) instead of manually
calling invalidateDisplayItemClientOnBacking. These two functions are
deceptively similar but invalidateDisplayItemClients is virtual and
can perform additional invalidations in some subclasses. One example is
LayoutInline which invalidates flow-box children in addition to itself.

This fixes a regression caused by [1] where fixed-pos changes would
only invalidate LayoutObject non-composited descendants and would forget
about its inline text friends.
