Introduce the following variables:
 - CI_MERGE_REQUEST_DIFF_ID
 - CI_MERGE_REQUEST_DIFF_BASE_SHA
behind a feature flag, ci_mr_diff_variables.

For testing, remove the context 'when source project does not exist'
because the factory creates the pipeline in the source project. Also
differentiate between detached and merged results pipelines.
