Support pre-authorization workflow

After some additional years of implementing/using/debugging/patching Commerce payment gateways, I now see that we have used the payment workflow states in a uncommon way. We were using the authorization state for sole payment intents, where the payment and order process hasn't finished yet. It works very good internally, but upon implementing this task, this is causing a lot of problems for us. So we have first to correct the worklow (use "new" instead auf "authorization" for payment intents, then implement the two different workflows)

solved as part of #3454250-4: [META] 2.x roadmap →
