GCD design updates based on AutoTuner runs

[jeffng-or]

Updated GCD autotuner.json and configs/SDCs based on AutoTuner runs. The clock periods in the SDC files should now be within the AutoTuner config range.

Enabled DRT antenna repair for ihp-sg13g2 in gcd config file temporarily. The proper spot is in the ihp-sg13g2 platform config.mk, but that will come in a different PR.

Updated metadata and rules files for designs. Here are the metric changes:

@vvbandeira , any idea why the pr-merge CI failed in the cleanup stage?
