iris/ci: Add manual jobs for tracking performance

Use Piglit's replay profile to measure and store the time that frames take to render in the GPU.

This job won't run automatically in regular pipelines, but will be triggered automatically by a script for every successful pre-merge pipeline.

This is because we want to generate performance data for every relevant commit merged in main, but we don't want to keep a device busy during the pre-merge run.
