[SpecPOWER] Invalidate and update SPECPower data

[ArneTR]

• Some new measurements have been released that we need to feed into our model: 2022Q4 and 2023Q1
• https://spec.org/power_ssj2008/results/
• Also some results have been invalidated. It would make sense to remove them from our model: https://spec.org/power_ssj2008/results/res2015q3/power_ssj2008-20150708-00698.html
