freedreno/ci: Add a manual job for tracking performance

freedreno/ci: Add a manual job 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.
