Set ignore flag during deferred savelayer

bug:8471552

Additionally, add ignore check for draw functor

In deferred mode, if we don't set ignore, a 0 alpha displayList won't
be quickRejected, and not only would its contents be needlessly
deferred, but upon playback any functors would be drawn, ignoring the
state of the snapshot.
