Don't constrain invalidation rect when not clipping children

View.setClipChidlren(false) allows children to draw outside of their containers.
But logic in ViewGroup.invalidateChildInParent() constrains the invalidation
rectangle to the bounds of the parent, making the flag useless in some situations.
Avoid intersecting the dirty rect with the parent bounds when the parent
is set to not clip its children.
