convert fullstack ghprb PR test job to prow job

This commit:
 - Configures both the PR and the periodic fullstack jobs to use the
   dynamic pipeline script.
 - Adds Prow specific parameters for both the PR and periodic fullstack
   test jjbs.
 - Removes the IPA_REF parameter from both the PR and the periodic fullstack
   jobs as that parameter will have no role in the future in the IPA building.

Notes:
 - The PR fullstack test is planned to be triggered by Prow.
