Clear latched invalidation state for a <marker> when painting

We keep track of invalidations in
LayoutSVGResourceContainer::completed_invalidations_mask_ to reduce the
amount of propagation performed. These flags are then usually cleared on
subsequent accesses later during the lifecycle. For non-layout
invalidations of markers the latched state would however not be cleared.

Clear the latched state when we (try to) paint a marker.
