23c free - spfile parameter changes

In the newly Oracle version 23c (available - but not yet production ready) some spfile parameters appeared (and disappeared) in comparison to 21.9. 
Most of these parameters are undocumented, so it will take some time to understand their impact. 
Still I prefer to have this list available and visible, so it's easier to understand changes and their impact when analyzing them. 

843 new parameters are:
