remove PipelineStatus and PipelineResourceStatus

This removes two struct types:

* `PipelineStatus`
* `PipelineResourceStatus`

These Status types were unused and did not follow the pattern of using
Knative's DuckType. Other types such as `Task` do not have a Status type
and instead defer to their corresponding `TaskRun` status.

fixes #1636
