Update dependencies and build order in Bender.yml, use non-deprecated clk_gating

Hi @FrancescoConti,
I hope these changes are ok, please let me know if you have questions.
If possible, it would be great to have a release of this repository once merged, I believe v1.6.2 could make sense.

Only comment is on the cluster_clock_gating, I hope it does not break integration with other flows -- but let's merge anyways. The CG cell model itself is absolutely identical, so we'll solve that possible problem when it occurs :)
