Move internal Pipeline::Stop() call to WMPI

Currently, almost all calls to Pipeline's public interface first pass
through PipelineController. The one exception is that Pipeline calls its
own Stop() in OnError().

This CL moves the internal Pipeline's calls to Stop() out to WMPI. This
gives PipelineController an opportunity to adjust its internal state
appropriately. It also makes Pipeline easier to reason about, since it
doesn't change its own state.
