update_engine: Pass Action ownership to ActionProcessor

Currently, an object that uses an ActionProcessor for processing one or more
actions has to own the Actions. This is problematic, because if we want to
create an action on the fly and use an ActionProcessor to perform it, we have to
own the Action until it is finished. Furthermore, if someone forget to own the
action, there will be memory leaks because ActionProcessor does not delete the
Action.

This patch passes the ownership of the Actions to the ActionProcessor through
unique pointers. If an object wants to have access to the Action, it can get it
when ActionComplete() is called.
