Show Param Values Added by Pipelines Controller for PipelineRun/TaskRun Describe

Feature request

The ability to see param names/values added by the pipelines controller as opposed to by the user when using tkn pipelinerun desc or tkn taskrun desc. The pipelines controller will add param values in the case of default values for params that are part of a Task or Pipeline.

If no value is declared for a param for a PipelineRun/TaskRun and the associated Task or Pipeline has default values for params, the default values are used and added to the PipelineRun/TaskRun status.

Currently, describe commands for PipelineRun/TaskRun only show param values that are part of the spec of a PipelineRun/TaskRun, but they should also show default values added by the controller.

See more in #1036 for discussion of this.

Use case

Seeing all param values that are part of a PipelineRun/TaskRun to aid with development/debugging PipelineRuns/TaskRuns.
