Add predefined variables to fetch the information of upstream job (Cross-project pipeline)

Description

For fetching the information of the upstream job, there are two solutions.

• Add predefined variables to fetch the information of upstream job (Cross-project pipeline)
• Pass/get variables with $CI_JOB_TOKEN pipeline triggers

This issue focuses on the first approach.

Proposal

Add predefined variables to fetch the information of upstream job (Cross-project pipeline)

The trigger could automatically pass, in addition to CI_PIPELINE_SOURCE=pipeline, other information like project id, pipeline id, job id... from which in principle branch and commit could be obtained.
